血手印的荧光显现

Fluorescence Development of Blood Fingerprint

本文在比较使用联苯胺及其衍生物显现血手印的同时 ,提出了采用荧光显现试剂显现血手印的新方法 ,文章在简述血红蛋白的组成和性质 ,通过强氧化剂破坏血红素、沉淀珠蛋白、采用激活血痕、蛋白染色的方法 ,使血手印清晰显出 ,并先后开发出用于潜血手印显现的十五种荧光试剂。文章系统论述了血手印荧光显现的原理 ,讨论了影响血手印荧光显现的各种因素 ,说明了活化血痕、蛋白染色显现血手印方法、主要特点和显现效果。

In this article we compared benzidine with derivative methods of developing blood fingerprint and put forward a new fluorescence method. Combination and nature were briefly discussed. Blood fingerprint was developed distinctly through strong oxidation agent destroying ferroheme, depositing pearl protein by blood stain activation and protein decoration method. Fifteen fluorescence agents for developing latent blood fingerprint were exploited. Development theory of blood fingerprint was discussed systematically, including all kinds of affected factors of blood fingerprint fluorescence development. The method, main characteristics and developing effect of blood stain activation and protein decoration for developing blood fingerprint were explained.
