本文应用国产两性电解质等电点聚焦法(PAGIEF)对1个月的40种动物血痕浸出液及经PCMB处理后的血痕浸出液的谱型进行了研究。根据谱型特征,成人除与人胎儿及猴难以鉴别外,与其它动物均可鉴别。动物间除鸟纲,鱼纲内有五组动物组内难以鉴别外,其它均能鉴别。经PCMB处理后,成人与人胎儿的谱型仍无差别,与其它动物的鉴别则更容易。结果表明,国产两性电解质用于等电聚焦进行血痕的种属鉴别是完全可能的。
In this paper, the domestic amphoteric electrolyte isoelectric point focusing method (PAGIEF) was used to study the profiles of 40 kinds of animal blood-stain leachate and PCMB-treated bloodstain leachate in one month. According to the spectral features, adults are difficult to identify with human fetuses and monkeys, and can be identified with other animals. Among the animals, there are five groups of animals that are difficult to differentiate within the group except for the order Birdwatching. Other species can be identified. After PCMB treatment, adult and human fetal spectrum is still no difference, and other animal identification easier. The results show that domestic amphoteric electrolyte for isoelectric focusing species identification of bloodstains is entirely possible.
