甲胎蛋白(AFP)是一种含有N—连接的双糖链分子结构的糖蛋白,可来源于胎儿肝脏和卵黄囊。不同来源的AFP在糖链结构上存在一定的区别,这种分子结构上的差别可通过植物凝集素与其不同的亲和力将其检出。通常将这种不同构型的AFP称为AFP异质体或亚型。在成人应用AFP异质体检
Alpha-fetoprotein (AFP) is a glycoprotein that contains an N-linked disaccharide molecular structure that can be derived from the fetal liver and yolk sac. Different sources of AFP in the sugar chain structure there is a certain difference, this molecular structure differences can be detected by phytohemagglutinin and its different affinity. This different configuration of AFPs is commonly referred to as AFP heterogeneous or subtype. AFP heterogeneous physical examination in adults
