Multiplex Sets for the Amplification of Polymorphic Short Tandem Repeat Loci — Silver Stain and Fluorescence Detection

Abstract

Multiplex PCR amplification systems were developed using well-characterized, polymorphic short tandem repeat (STR) loci. Eight loci utilized in the multiplex amplifications included HUMCSF1PO, HUMTPOX, HUMTH01, HUMVWFA31, HUMF13A01, HUMFESFPS, HUMBFXIII and HUMLIPOL. From this list, three or four non-overlapping loci were simultaneously amplified, separated by denaturing polyacrylamide gel electrophoresis and visualized using silver stain or fluorescence detection. The multiplex PCR amplification systems offer a non-isotopic method for rapid, simple and accurate analysis of STR loci. This high-throughput method for DNA identification has immediate and valuable application in forensic analysis, paternity determination, tissue culture strain identification and bone marrow transplantation studies.
