PCR-based human leukocyte antigen (HLA) DQ alpha typing of blood stained light and dark blue denim fabric.

Abstract excerpt

Obtaining typable PCR products from DNA purified from blood stained blue denim has been difficult since inhibitors of PCR in blue denim apparently co-purify with the DNA. Organic and chelex extraction methods were tested for their ability to purify typable DNA from either light or dark blue denim fabric both stained with blood. DNA purified from the light blue denim using either method was successfully used in...
