vmrd抗體應(yīng)用在行業(yè)中具有多少種分類？
發(fā)布時(shí)間： 2020-05-27 點(diǎn)擊次數(shù)： 1270次vmrd抗體是B細(xì)胞接受抗原刺激后增殖分化為漿細(xì)胞所產(chǎn)生的糖蛋白，主要存在于血清等體液中，是介導(dǎo)體液免疫的重要效應(yīng)分子，能與相應(yīng)抗原特異性結(jié)合，發(fā)揮免疫功能。vmrd抗體分類：vmrd抗體是一類能與抗原特異性結(jié)合的免疫球蛋白。vmrd抗體按其反應(yīng)形式分為凝集素、沉降素、抗毒素、溶解素、調(diào)理素、中和抗體、補(bǔ)體結(jié)合抗體等。按抗體產(chǎn)生的來源分為正常抗體，如血型ABO型中的抗A和抗B的抗體，和免疫抗體如抗微生物的抗體。按反應(yīng)抗原的來源分為異種抗體，異嗜性抗體，同種抗體和自身抗體。按抗原反應(yīng)的凝集狀態(tài)分為*抗體IgM和不*抗體IgG等。vmrd抗體在醫(yī)療實(shí)踐中應(yīng)用甚為廣泛。如用于疾病的預(yù)防、診斷和治療方面都有一定的作用。臨床上用丙種球蛋白預(yù)防病毒性肝炎、麻疹、風(fēng)疹等，上用抗Rh免疫球蛋白預(yù)防因Rh血型不合引起的溶血癥。診斷上如類風(fēng)濕因子用于類風(fēng)濕性關(guān)節(jié)炎，抗核抗體(ANA)、抗DNA抗體用于系統(tǒng)性紅斑狼瘡，抗精子抗體用于原發(fā)性不孕癥的診斷等；治療上如毒素中毒用抗毒治療以及免疫缺陷性疾病的治療等。vmrd抗體的基本結(jié)構(gòu)：經(jīng)x線晶體衍射結(jié)構(gòu)分析發(fā)現(xiàn)，Ig由四條多肽鏈組成，各肽鏈之間南數(shù)量不等的鏈間二硫鍵連接。Ig可形成“Y”字型結(jié)構(gòu)，稱為Ig單體，是構(gòu)成抗體的基本單位。
