The amplification fragment length polymorphisms (Amp-FLPs) of short tandern repeat (STR) locus ACTBP2 were studied by polymerase chain reaction (PCR) technique and denatured polyacrylamide gel electrophoresis(PAGE) followed by silver staining.

• 应用变性聚丙烯酸胺凝胶电泳（dn－PAGE）结合银染色技术对短串联重复（STR）位点ACTBP2（SE33）的扩增片段长度多态性（Amp－FLPs）进行了研究。
