HumanPlacentalAlkalinePhosphataseStain
The following protocol is for detection of human placental alkaline phosphatase (AP) in cultured cells. Human placental AP is heat stable, unlike other AP proteins typically expressed by cells. A few cell types (HeLa cells, for example) express high background levels of heat-stable AP making detection of introduced AP difficult, but most cells have suitably low AP background.1. FIX: Aspirate culture medium and f......阅读全文

碱性磷酸酶(alkaline－phosphatase,－ALP)的分离与纯化
一、实验目的1.掌握酶分离纯化的一般步骤及相关原理；2.悉碱性磷酸酶的分离纯化的方法步骤。二、实验原理有机溶剂分级沉淀是分离蛋白质的常用方法之一。有机溶剂能使许多溶于水的酌生物大分子发生沉淀，其主要作用是降低水溶液的介电常数。例如20℃时水的介电常数为80，82％的乙醇溶液的介电常数为40。溶液的介

关于颅内生殖细胞瘤的肿瘤标志物检查介绍
肿瘤标志物为肿瘤产生的生物学物质，它的存在可指示出某种肿瘤的存在，如生殖细胞瘤产生不同种类的胚胎蛋白。因肿瘤细胞产生的标记产物直接进入脑脊液中，故脑脊液中肿瘤标记物的浓度常为血液的8－10倍，有些患者可高达30～40倍。良性畸胎瘤的肿瘤标记物为阴性。因多数生殖细胞瘤都伴有颅内压增高，较难获取CS
