The Fastest, Simplest, and Most Effective Way to Remove DNA Contamination

TURBO DNA-free Kit
Orders of magnitude better DNA removal than with wild type DNase I

Perform DNA digestion and sample clean-up in just 20 minutes

Preserve RNA quality

DNase treatment is the method of choice for the removal of contaminating genomic DNA from RNA samples in preparation for RT-PCR. TURBO DNase (patent pending) is an engineered variant of DNase I with a 6-fold lower Km for DNA than wild type DNase I. As a result, TURBO DNase is a superior enzyme for removal of trace amounts of contaminating DNA from RNA preparations. Using the TURBO DNA-free Kit, DNA digestion and the subsequent removal of DNase and divalent ions from the RNA sample, can be accomplished within 20 minutes.

We compared the TURBO DNA-free Kit with a popular wild type DNase I enzyme (Competitor P). To highlight the benefits of TURBO DNase, total RNA was purified from mouse spleen, a notoriously DNA-rich tissue, using a procedure that results in significant contamination with genomic DNA. An 8 g sample of spleen RNA was then digested for 15 min at 37C with 12 U of TURBO DNase or 12 U of DNase I from Competitor P in a 100 l reaction. Reactions were then processed as instructed by the TURBO DNA-free Kit Instruction Manual o
