What is the difference between the QIAamp UCP DNA Micro Kit (cat. no. 56204) and RNeasy UCP Kits (cat. no. 73934) and non-UCP QIAGEN purification kits?

UCP kits contain UCP MinElute columns.  These columns are decontaminated from exogenous DNA and RNA. The complete kit is tested under stringent QC to ensure minimal microbial DNA / RNA levels at the time of delivery.
