| 摘 要： | 本文报道用体外DNA扩增技术对3例刑事案中的人血痕标本进行性别鉴定。其方法是从血痕标本中微量抽提DNA,用蛋白酶K进行消化。然后用两组引物Y1.1与Y1.2和Alu9.1与Alu9.2及国产FD耐热DNA聚合酶进行聚合酶链反(PCR)扩增DNA,电泳分析Y及Alu重复序列,从而判断血痕的性别。

| Abstract: | This paper reports the determination of sex of human blood stains in threecriminal cases by the DNA amplification technique.The results fit the cases de-tails and gave the scientific evidence for the justice.The blood stains were dige-sted with proteinase K.The protein was extracted with the phenol-chloroform.The DNA was precipitated with NaCl and ethyl alcohol.Amplification of DNAwas carried out using two pairs of primer Y1.1 Y1.2 and Alu9.1 Alug.2 and heatstable FD polymerase.The amplified products were subjected to agarose gel(con-taining ethidium bromide)electrophoresis.Sex of blood stains was determinedaccording to the amplified products.PCR technique is rapid to perform,sensitiveand simple.No special equipments and isotope labelled probe are required. |
