An improved method for STR analysis of bloodstained denim.

Abstract excerpt

Indigo dye is used to dye denim and other fabrics. It is now accepted that if this is co-extracted with the DNA, it may inhibit PCR amplification. A simple, improved method is described for the extraction of DNA from bloodstained denim for PCR amplification and short tandem repeat (STR) analysis. The DNA was extracted by constructing a blotting system using capillary action to draw a saline solution through the...
