抗体（antibody）的功能
一、识别并特异性结合抗原（Recognition and bind antigen specifically ） 识别并特异性结合抗原是免疫球蛋白分子的主要功能，这种特异性主要是由免疫球蛋白V 区的空间构型所决定。免疫球蛋白分子有单体、二聚体和五聚体等几种所谓的体形式。只有1 个Y 形分子组成
抗体结构（antibody－structure）
抗体（antibody，Ab）是机体免疫细胞被抗原激活后，由分化成熟的终末B细胞--浆细胞合成、分泌的一类能与相应抗原特异性结合的具有免疫功能的球蛋白。 抗体是具有4条多肽链的对称结构，其中2条较长、相对分子量较大的相同的重链（H链），含450?550个氨基酸残基，相对分子质量在 55000?7

单克隆抗体制备(McAb－production)的基本过程
抗原提纯与动物免疫 对抗原的要求是纯度越高越好，尤其是初次免疫所用的抗原。如为细胞抗原，可取1×107个细胞作腹腔免疫。可溶性抗原需加完全福氏佐剂并经充分乳化，如为聚丙烯酰胺电泳纯化的抗原，可将抗原所在的电泳条带切下，研磨后直接用以动物免疫。 选择与所用骨髓瘤细胞同源的BALB/c健康小鼠，

单克隆抗体(monoclonal－antibody)克隆化技术
经过抗体测定的阳性孔，可以扩大培养，进行克隆，以得到单个细胞的后代分泌单克隆抗体。克隆的时间一般说来越早越好。因为在这个时期各种杂交瘤细胞同时旺盛生长，互相争夺营养和空间，而产生指定抗体的细胞有被淹没和淘汰的可能。但克隆时间也不宜太早，太早细胞性状不稳定，数量少也易丢失。 克隆化的阳性杂交瘤细胞，经
