| 摘 要： | 目的扩增常见动物TP53内含子8片段,确定其在法医学生物检材种属鉴定中的应用价值。方法收集标本为包括人在内的15种常见动物的血痕或肌肉组织,提取DNA后定量,应用PCR扩增TP53内含子8,PAGE电泳,银染后观察结果。结果人和猕猴都扩增出一条长度为460bp的片段,鳝鱼、鲢鱼、青蛙、鸭、兔、猫、小白鼠、豚鼠、猪、牛、羊虽有扩增产物,但不在分型区内,鸡、狗未见扩增产物。结论扩增TP53内含子8进行种属鉴定,方法简单,灵敏度较高。

| Abstract: | Objective To identify the species of biological samples by amplifying intron 8 of the TP53gene. Methods Collected the bloodstains or muscle tissues of 14 kinds of common animals and human.DNA were quantified after extraction.The PCR amplification products were analyzed by PAGE and silverstaining. Results The human and monkey have one amplification band of 460bp while the eel,fish,frog,duck,rabbit,cat,mouse,cavy,pig,ox and sheep could amplify different unspecial bands.No amplificationproducts were found in chicken and dog. Conclusion The method of species identification by amplifyingintron 8 of the TP53 gene is simple and sensitive. |
