Genomic Sample Prep


Superior Substitute to Phenol/Chloroform for Hemoglobin & Protein Removal, Isolation of DNA/RNA

  • Removes protein contaminants & leaves DNA & RNA soluble and unreacted
  • Ideal for applications when the alternative kits don’t fit, or are not optimal
  • Adaptable to any sample size and can be automated
  • Pathogen and infectious disease testing

Sample Type ProCipitate Typical Usage
1 mm Plant Leaf 50 µl
2.0 ml culture BAC Preps 80 µl
5µm paraffin-embedded tissue 200 µl
Dried Blood Card or ~ 40 µl Whole Blood 400 µl

PCR from whole blood using ProCipitate

PCR from whole blood using ProPrep Genomic kit

Lane 1: 100-1000 base pair Ladder

Lane 2: Negative Control

Lanes 3-10:
PCR amplicons from 1 ng template DNA purified from whole blood, randomly selected from 96 wells. Amplicons are 280 base pairs from Human HLA-DRBeta primers at 32 cycles.
