Product Details

AllPrep DNA/RNA Kits enable simultaneous purification of genomic DNA and total RNA from each cell or tissue sample. Since there is no need to divide each sample into two for separate purification procedures, maximum yields of DNA and RNA can be achieved. The purified DNA and RNA are eluted separately.

The AllPrep DNA/RNA Micro and Mini Kits can be automated on the QIAcube Connect. The AllPrep DNA/RNA 96 Kit is well suited for high-throughput purification of genomic DNA and total RNA from up to 96 samples.

Performance

Small samples of cultured cells and easy-to-lyse tissues can be processed with AllPrep DNA/RNA technology (see table “Optimal yields of DNA and RNA from tissues using the AllPrep DNA/RNA Micro Kit”). Genomic DNA is purified using the novel AllPrep DNA spin column, and total RNA is purified using an RNeasy MinElute spin column. Total RNA with Agilent RIN values of close to 10 is routinely obtained from cultured cells. Genomic DNA and total RNA show reliable quantification over a wide dynamic range (see figure " Wide dynamic range").

Optimal yields of DNA and RNA from tissues using the AllPrep DNA/RNA Micro Kit

Tissue (5 mg)	DNA yield (µg)*	RNA yield (µg)*
Heart	3.89	2.00
Brain	2.60	3.08
Kidney	11.33	12.70
Liver	32.40	16.02
Lung	9.65	24.63
Spleen	20.50	43.51
Thymus	34.90	56.89
Intestine	26.71	27.38

* DNA and RNA were purified from two 5 mg samples of each tissue, and the average yields are shown.

A simple workflow allows DNA and RNA extraction from one sample. The purified genomic DNA has an average length of 15–30 kb and performs well in multiplex PCR (see figure "Multiplex PCR of 8 targets"). Total RNA is of high quality and has a RIN value of 10 indicating that the RNA is intact (see figure " Simultaneous purification of total RNA and genomic DNA" and figure " High-quality total RNA").

AllPrep DNA/RNA technology also enables efficient purification of high-quality DNA and RNA from different cell and tissue types in convenient 96-well format (see table “High-quality RNA from tissues purified using the AllPrep DNA/RNA 96 Kit” and figure " Reproducible purification of DNA and RNA in 96-well format").

Principle

AllPrep DNA/RNA Kits are designed to purify both genomic DNA and total RNA from the same cell or tissue sample. Since there is no need to divide the sample into two for separate purification procedures, maximum yields of DNA and RNA can be achieved. Efficient purification of high-quality DNA and RNA from different tissue types is achieved without the need for additional RNase or DNase digestion. The purified DNA and RNA are eluted separately and ready to use in any downstream application. Processing in 96-well format makes AllPrep DNA/RNA technology the ideal tool for sample preparation in genomics and systems biology.

For a more sustainable alternative, we have the QIAwave DNA/RNA Mini Kit. This kit reduces plastic and cardboard usage by up to 52% and 58%, respectively compared to the AllPrep DNA/RNA Mini Kit. It features waste tubes made from 100% recycled plastic, which can be reused throughout the procedure. The QIAwave buffers, in concentrated form, cut down plastic consumption by up to 90% per bottle. Despite the visual difference, the QIAwave Kit maintains user-friendliness with chemistry and performance identical to the standard kit.

In partnership with My Green Lab, we've also assessed the environmental impact of the AllPrep DNA/RNA Mini Kit (50) and the QIAwave DNA/RNA Mini Kit (50). My Green Lab ACT environmental impact factor labels aim to assess and rate products based on various sustainability criteria, including:

Manufacturing
Responsible chemical management
Sustainable content within products and packaging materials
Disposal of the packaging at the end of life

Products are scored from 1 to 10 except for energy and water consumption, which are scored as 1 point per kWh or gallon, respectively. A low score means a lower environmental impact (see figures "DNA/RNA Mini Kits (50) environmental impact factor label   US,   EU and   UK").

Procedure

A simple spin-column workflow allows the purification of high-quality DNA and RNA from the same sample (see flowchart “ AllPrep DNA/RNA procedure”). Both cultured cells and easy-to-lyse tissues can be processed. Genomic DNA is purified using the novel AllPrep DNA spin column, and total RNA is purified using an RNeasy Mini or RNeasy MinElute spin column (AllPrep DNA/RNA Micro Kit).

When disrupting and homogenizing tissues in Buffer RLT Plus (supplied with the AllPrep DNA/RNA Micro Kit and Allprep DNA/RNA Mini Kit), excessive foaming may occur (please note this is not the case for the Allprep DNA/RNA 96 Kit since this product is supplied with Buffer RLT). This foaming is substantially reduced by adding Reagent DX (supplied separately) to Buffer RLT Plus at a final concentration of 0.5% (v/v) before starting disruption and homogenization. Reagent DX has been carefully tested with the kits, and has no effect on RNA purity or on downstream applications such as real-time RT-PCR. Buffer RLT Plus containing Reagent DX can be stored at room temperature (15–25ºC) for at least 9 months.

A supplementary protocol allows optional purification of protein. For experiments where DNA, RNA, and protein are regularly prepared from each sample, the AllPrep DNA/RNA/Protein Mini Kit can be used instead.

For high-throughput processing, the 96-well purification plates of the AllPrep DNA/RNA 96 Kit are for both DNA and RNA. The plates are rapidly and conveniently processed using either a centrifuge (Centrifuge 4-16 and Plate Rotor 2 x 96) or a combination of vacuum (QIAvac 96) and centrifuge. Both cultured cells and easy-to-lyse tissues can be processed.

AllPrep DNA/RNA Kits form part of QIAGEN's solution for preparing multiple analytes from the same sample. These include Allprotect Tissue Reagent, which stabilizes DNA, RNA, and protein in tissues, and RNAprotect Cell Reagent, which stabilizes DNA and RNA in cells. Both reagents deliver immediate stabilization at room temperature. For tissues, TissueRuptor and TissueLyser systems provide fast disruption at low- to high-throughputs.

Applications

The purified genomic DNA has an average length of 15–30 kb, depending on homogenization conditions, and is suited for any application, including next-generation sequencing, Southern-, dot-, and slot-blot analyses; and PCR and multiplex PCR.

The purified total RNA can be used in any application, such as RNA-seq RT-PCR and real-time RT-PCR; differential display; cDNA synthesis; northern-, dot-, and slot-blot analyses; and microarrays.

A supplementary protocol allows optional purification of protein. The purified protein is denatured and can be used in applications such as SDS-PAGE, western blotting, and 2D gel electrophoresis.

FAQ ID - 3560

Up to 1 x 10e6 cells or up to 5 mg tissue can be processed with the Allprep DNA/RNA 96 Kit when following the vacuum/spin protocol, or up to 2 x 10e6 cells or 10 mg tissue using the spin protocol.

FAQ ID -1997

Yield and integrity of genomic DNA depend on the disruption and homogenization method used with the Allprep DNA/RNA Kits.

Homogenization with the TissueRuptor (or other rotor–stator homogenizer, such as the Polytron) or the TissueLyser results in greater DNA fragmentation (depending on homogenization time and intensity). However, shorter DNA fragments are easier to elute, so DNA yields will be higher.

In contast, homogenization using the QIAshredder (or a syringe and needle) is more gentle, resulting in less DNA fragmentation. However, longer DNA fragments are more difficult to elute, so DNA yields may be lower.

FAQ ID -1751

The main difference between these buffers is that Buffer RLT Plus contains additional detergents. Buffer RLT Plus is optimized for efficient binding of DNA to the AllPrep DNA spin column. However, the AllPrep DNA 96 plate in the Allprep DNA/RNA 96 Kit behaves slightly different than the AllPrep DNA spin column in the AllPrep DNA/RNA Mini Kit, and achieves better specificity with Buffer RLT.

FAQ ID -1999

For easy-to-lyse tissues, AllPrep DNA/RNA Kits can be used. For biopsies of 5–30 mg, we recommend using the AllPrep DNA/RNA Mini Kit. For smaller biopsies, we recommend using the AllPrep DNA/RNA Micro Kit instead.

For examples of different cell lines and tissue types tested with these kits, and their average yields of DNA and RNA, please see Table 2 of the AllPrep DNA/RNA Micro and AllPrep DNA/RNA Mini Handbook.

FAQ ID -1089

Yes, please follow the Supplementary Protocol Acetone precipitation of protein from Buffer RLT or Buffer RLT Plus lysates (RY22).

Important Note:

Do not use TCA to precipitate protein from Buffer RLT and Buffer RLT Plus lysates. These buffers contain guanidine thiocyanate, which can form highly reactive compounds when combined with acidic solutions.

For simultaneous purification of DNA, RNA, and protein from the same sample (either cultured cells or easy-to-lyse tissues), we recommend using the AllPrep DNA/RNA/Protein Mini Kit. This kit allows precipitation of protein from Buffer RLT lysates using a novel protein precipitation buffer, Buffer APP.

Please note that Buffer APP is not compatible with Buffer RLT Plus. Acetone should be used instead to precipitate protein from RLT Plus lysates.

FAQ ID -1164

When using the RNeasy Plus Micro and RNeasy Plus Mini Kits, or the Allprep DNA/RNA Mini Kit, foaming of lysates can be substantially reduced by adding Reagent DX to Buffer RLT Plus at a final concentration of 0.5% (v/v) before starting sample lysis.

Reagent DX has been carefully tested with RNeasy Plus and Allprep Kits and has no effect on RNA purity or on downstream applications. Reagent DX can be purchased separately using catalog number 19088.

For more information on efficient sample disruption and homogenization for nucleic acid extractions, please see further product details and resources for the TissueRuptor, TissueLyser LT, and TissueLyser II.

FAQ ID -1734

No. Tissue lysis generates more debris than cell lysis. This additional debris is not compatible with the special binding conditions for small RNAs using the Allprep DNA/RNA 96 Kit, and can lead to a reduction of up to 50% or more in RNA yield.

FAQ ID -2001

No, our standard RNeasy Mini Kit will not be discontinued. The Allprep DNA/RNA Mini Kit is an addition to our RNeasy product line.

FAQ ID -1054

Tissue-Tek O.C.T. is an embedding compound for cryosectioning, which is soluble in water. It mainly consists of glycols and synthetic resins. Tissue-Tek O.C.T. is used as matrix for cryosectioning of tissues. Using the O.C.T. the tissue samples can be positioned more easily in the microtome and have better qualities during sectioning.

Most cryosections are fixed using non-crosslinking agents. For isolation of RNA from tissue embedded in Tissue-Tek O.C.T. using non-crosslinking agents the RNeasy Plus Micro Kit or the RNeasy Micro Kit (Protocol: Total RNA Isolation from Microdissected Cryosections), or the RNeasy Mini Kit (RNeasy Mini Protocol for the isolation of Total RNA from Animal Tissue) give great results. We strongly recommend removing as much of the embedding compound as possible prior to RNA extraction from the sections. Please see QIAGEN News article, Issue 1 1998, 'Effects of malnutrition on expression of lactase in children' for successful RNA isolation from O.C.T.-embedded tissue using the RNeasy Mini Kit.

In case crosslinking agents (e.g. formaldehyde or glyoxal-containing) were used for fixation of the tissue for cryosectioning the RNeasy FFPE Kit is the perfect choice. The RNeasy FFPE Kit is especially designed for purifying total RNA from formalin-fixed tissue sections. Special lysis and incubation conditions reverse formaldehyde modification of RNA for improved results in downstream application. The crosslinking causes the RNA to break, resulting in overall smaller molecules, which look like a smear when analyzed on a formaldehyde gel.

In case DNA as well as RNA from precious samples is of interest from the identical sections, please have a look at the AllPrep DNA/RNA Kits for unfixed tissue or the AllPrep DNA/RNA FFPE Kit for fixed tissue.

FAQ ID -530

In our labs, we were able to purify RNA using the RNeasy Plus Micro Kit, or DNA/RNA using the AllPrep DNA/RNA Micro Kit at single cell level. However, generally we do not recommend purification from fewer than 10–20 cells, due to stochastics related to transcript copy numbers present in a single cell.

For example, if an RNA transcript is present at only 1 copy per cell, recovery from a purification using e.g., 10 cells or less, would be less than 1 transcript copy per microliter, given the recommended elution volume of 14 µl.

FAQ ID -1750

No, Buffer APP for protein precipitation in the Allprep DNA/RNA/protein Mini Kit is not compatible with Buffer RLT Plus. Acetone can be used to precipitate proteins from samples homogenized in Buffer RLT Plus contained in the Allprep DNA/RNA Mini Kit and RNeasy Plus Mini Kit.

FAQ ID -1577

Buffer RLT Plus contains detergents that are more ideal for binding of DNA to the AllPrep DNA mini spin columns.

But RLT Plus is not compatible with Buffer APP used to precipitate proteins in AllPrep DNA/RNA/Protein Mini kit. Therefore, we chose RLT instead of RLT Plus to get both DNA and proteins with this kit.

RLT lysates can also be used in AllPrep RNA/DNA kit or the AllPrep DNA/RNA Micro kit. DNA and RNA yields should be fine, but RNA may contain slightly higher levels of genomic DNA contamination.

FAQ ID - 3391

Yes, RNAs smaller than 200 nucleotides, including miRNA, can be isolated using the AllPrep DNA/RNA Micro or RNeasy Plus Micro Kit. Please follow the specialized protocol 'Purification of total RNA containing small RNAs from cells' in Appendix D of the AllPrep DNA/RNA Micro or the RNeasy Plus Micro Handbook, respectively.

Please note that this protocol is for use with cultured cells only, and is not compatible with tissues.

FAQ ID -1749

The Allprep DNA/RNA 96 kit is designed for cultured human or animal cells, and for easy-to-lyse human or animal tissues. Tissues compatible with RNeasy Mini, RNeasy Plus Mini, and RNeasy Plus 96 are also compatible with the Allprep DNA/RNA 96 kit.

For more information on compatible kits and sample types, see our Selection Guide for RNA purification.

FAQ ID -1996

In principle, it is possible. However, the efficiency of DNA binding to the AllPrep DNA 96 plate should be high enough so that no additional DNA removal/digestion is required.
