[Distribution of CSF1PO, TPOX and TH01 loci in Han Chinese].

The application of short tandem repeat (STR) polymorphisms has stimulated progress in the elaboration of linkage maps, forensic identification and paternity determination, characterization of disease genes, and simplification and precision of DNA typing. In this report. We have carried out DNA extraction from blood multiplex amplification of CSF1PO, TPOX and TH01. By using denaturing polyacrylamide gel electrophoresis and silver stain, we investigated the allele frequencies of CSF1PO, TPOX and TH01 loci in Han group living in Yunnan provice of China. In this study, 9 alleles and 22 genotypes of CSF1PO locus were observed; In the locus TPOX, 6 alleles and 14 genotypes were observed. In the TH01 locus, 6 alleles and 19 genotypes were observed.
