Viagen DirectPCR� DNA Extraction System is a single-tube system for rapid preparation of DNA from mouse tails, ear pieces, yolk sac, and culture cells. The patent-pending components developed by scientists at Viagen Biotech Inc. allow the resulting DNA extracts to be compatible with genomic PCR for genotyping. DirectPCR� system offers advantages over conventional protocols that include: � Time saving: Less hands-on time. Crude tail lysates for PCR. � Money saving: Cost-effective reactions. � Safe: No organic reagents. � Environmental: Less waste (organic reagents, tubes, tips, etc...) � Reliable and efficient: Virtually 100% success rate with high yields. 50ml (250 mouse tails).
