【操作】1、预染血清血清0.2ml中加苏丹黑染色液0.2ml，混合置37℃水浴中染色30分钟，离心（2000转/分）约5分钟。以除去悬浮于血清中染料沉渣。2、制备琼脂糖凝胶板将已配制好的0.5%琼脂糖凝胶于沸水浴中加热融化，用吸管吸取凝胶溶液浇注在载玻片上，约3 ml。静置半小时后凝固（天热时需延长
血清蛋白琼脂糖凝胶电泳(agarose－gel－electrophoresis)（一）
【原理】琼脂糖（agarose）是经过挑选，以质地较纯的琼脂（agar）作为原料而制成的。琼脂在化学上是由琼脂糖和琼脂胶组成的复合物。琼脂胶是一含有硫酸根和羟基的多糖，它具有离子交换性质，这种性质会给电泳及凝胶过滤以不良的影响。琼脂糖是直链多糖，它由D－半乳糖和3,6－脱水－L－半乳糖的残基交替排列

（3）电荷效应在分离胶中，各种血清蛋白所带静电荷不同，而有不同的迁移率。表面电荷多，则迁移快，反之则慢。因此各种蛋白质按照电荷多少、分子量大小及分子形状以一定顺序排成一个个区带。不连续PAGE所具有的分子筛效应、浓缩效应和电荷效应大大提高了它的分辨率。电泳后蛋白质染色目前常用的是考马斯亮蓝法，其比氨
