Abstract: Clear and high distinctive patterns of human DNA finger prints were obtained by using nonradioactive labelled probe Myo . The DNA fingerprints of 78 unrelated indiveduals living in Yunnan province of China were detected, and their probability of chance association between random individuals was calculated as 3. 4×10-10. It was higher than that by using radioactive 32 P labelled probe. The result of this study showed that the method by use of nontadioactive labelled probe was simple, fast, sensitive, reliabel and economical. The method can be broadly applied in forensic medicine and other fields.

Key words: nonradioactive label, probeMyo, DNA fingerprint, individual identification
