제품 세부 정보
The Qproteome Nuclear Protein Kit is designed for specific enrichment of nuclear proteins from cultured mammalian cells.
성능
The Qproteome Nuclear Protein Kit provides highly effective and reproducible separation of nuclear proteins as demonstrated using specific marker proteins (see figure " Reproducible, efficient separation of marker proteins"), which remain functionally active (see figure " Isolation of an active transcription factor").

원리
The Qproteome Nuclear Protein Kit is designed for specific enrichment of nuclear proteins from cultured mammalian cells. Lysis and centrifugation are used to separate the cytosolic fraction (supernatant) from the cell nuclei (pellet). A high-salt buffer allows dissociation of nuclear binding proteins (such as transcription factors) and their removal by diffusion from the nuclei.
절차
Cells are lysed and centrifuged to isolate nuclei. After washing, an extraction buffer is added to the nuclei and nucleic acid binding proteins dissociate from DNA and RNA. This soluble fraction is separated from the nuclear pellet by centrifugation. Proteins remaining in the pellet are solubilized using a second extraction buffer (see figure " Nuclear protein fractionation procedure").

응용 분야
The Qproteome Nuclear Protein Kit delivers a nucleic acid binding protein fraction suitable for a wide range of activity assays.
지원되는 데이터 및 수치
Isolation of an active transcription factor.
A biotinylated DNA oligo containing a specific transcription-factor binding sequence was immobilized on a streptavidin-coated 96-well plate. NX1 extraction buffer (Blank) or 10 µg nucleic acid binding protein fraction was added, washed, and detected colorimetrically in an ELISA procedure using a transcription-factor specific antibody. Specificity of binding was demonstrated by addition of a 10x excess of non-biotinylated oligo that was able to displace the transcription factor.
