title: [Distribution of three STR loci in Jingpo ethnic group in Yunnan province].
abstract: OBJECTIVE
  This study was aimed at the use of old blood stains for investigating the distribution of three STR loci in Jingpo ethnic group.
  
  
  METHODS
  DNA extraction from old blood stains (106 in number) and multiplex amplification of CSF1PO, TPOX and TH 01 were carried out. Using denaturing polyacrylamide gel electrophoresis and silver stain, the authors investigated the distribution of allele frequencies of CSF1PO, TPOX and TH01 loci in a Jingpo ethnic group in the southwestern part of Yunnan province.
  
  
  RESULTS
  7 alleles and 26 genotypes of CSF1PO locus,7 alleles and 19 genotypes of TPOX locus, and 6 alleles and 18 genotypes of TH01 locus were observed.
  
  
  CONCLUSIONS
  The satisfactory results demonstrate that multiplex amplification of CSF1PO, TPOX and TH01 is sensitive and the old stain of a drop of blood is sufficient for such amplification.
