vmrd抗體應用在行業中具有多少種分類？
發布時間： 2020-05-27 點擊次數： 1483次vmrd抗體是B細胞接受抗原刺激后增殖分化為漿細胞所產生的糖蛋白，主要存在于血清等體液中，是介導體液免疫的重要效應分子，能與相應抗原特異性結合，發揮免疫功能。vmrd抗體分類：vmrd抗體是一類能與抗原特異性結合的免疫球蛋白。vmrd抗體按其反應形式分為凝集素、沉降素、抗毒素、溶解素、調理素、中和抗體、補體結合抗體等。按抗體產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。按抗原反應的凝集狀態分為*抗體IgM和不*抗體IgG等。vmrd抗體在醫療實踐中應用甚為廣泛。如用于疾病的預防、診斷和治療方面都有一定的作用。臨床上用丙種球蛋白預防病毒性肝炎、麻疹、風疹等，上用抗Rh免疫球蛋白預防因Rh血型不合引起的溶血癥。診斷上如類風濕因子用于類風濕性關節炎，抗核抗體(ANA)、抗DNA抗體用于系統性紅斑狼瘡，抗精子抗體用于原發性不孕癥的診斷等；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抗體的基本結構：經x線晶體衍射結構分析發現，Ig由四條多肽鏈組成，各肽鏈之間南數量不等的鏈間二硫鍵連接。Ig可形成“Y”字型結構，稱為Ig單體，是構成抗體的基本單位。
