血红蛋白电泳（hemoglobin－electrophoresis）（HbA2定量）
实验原理血红蛋白电泳（hemoglobin electrophoresis）目的是检出和确认各种正常和异常的血红蛋白。根据不同的血红蛋白带有不同的电荷，等电点不同，在一定的pH缓冲液中，血红蛋白的等电点小于缓冲液的pH时带负电荷，电泳时在电场中向阳极泳动，反之，Hb带正电荷向阴极泳动。在一定电压下，

我们本次实验使用的是银染。银染的方法种类很多，目前有文献报道的就有100多种。但是其准确的染色机制还不是特别的清楚。大致的原理是银离子在碱性pH环境下被还原成金属银，沉淀在蛋白质的表面上而显色。 由于银染的灵敏度很高，可染出胶上低于1 ng/蛋白质点，故广泛的用在2D凝胶分析上。待找到自己感

一、蛋白质组学概论随着人类基因组计划的实施，生命科学步入了后基因组时代，出现了不同于以往经典生物实验科学的全新的研究方式─“生物大科学”。这种生物大科学的核心思想是整体性研究，即以生物体内某类物质为对象进行完整的研究。过去对生命活动的研究仅限于研究细胞内个别的基因或蛋白质，而基因组学和蛋白质组学的目

六、第二向 SDS-PAGE1．[基本原理]蛋白质在聚丙烯酰胺凝胶中电泳时，它的迁移率取决于它所带净电荷以及分子的大小和形状等因素。如果加入一种试剂消除电荷、形状等因素的影响，使电泳迁移率只取决于分子的大小，就可以用电泳技术测定蛋白质的分子量。1967年，Shapiro等发现在样品介质和聚丙烯酰胺凝
