什是抗體？抗體和單克隆抗體區(qū)別？

抗體(antibody)指機(jī)體的免疫系統(tǒng)在抗原刺激下，由B淋巴細(xì)胞或記憶細(xì)胞增殖分化成的漿細(xì)胞所產(chǎn)生的、可與相應(yīng)抗原發(fā)生特異性結(jié)合的免疫球蛋白。主要分布在血清中，也分布于組織液及外分泌液中。

抗體和單克隆抗體區(qū)別：
抗體分多克隆抗體和單克隆抗體。
抗體是針對(duì)某抗原表位的，多克隆抗體就是針對(duì)多個(gè)抗原表位的抗體，比如人體內(nèi)感染某抗原后產(chǎn)生的抗體，其實(shí)是多種抗體的混合物；單克隆抗體就是僅針對(duì)一個(gè)抗原表位產(chǎn)生的抗體，該抗體僅能結(jié)合一種特異性的抗原表位，比如說(shuō)生物書(shū)上經(jīng)常提到的單個(gè)漿細(xì)胞與骨髓瘤細(xì)胞的融合細(xì)胞所產(chǎn)生的抗體。
