compound introduction
在正常成人血清中，IgG相对于其亚类的近似百分比组成为IgG1:65%、Ig2:23%、IgG3:6%和IgG4:6%。一个或多个亚类的异常水平可能与自身免疫性、过敏性和肠道疾病以及复发性感染有关。 由骨髓瘤血浆制备，经美国食品药品监督管理局要求的测试显示，骨髓瘤血浆对HBsAg、抗HCV、抗HBc无反应，对抗HIV 1和2呈阴性。 In normal adult serum, the approximate percentage composition of IgG with respect to its subclasses is IgG1:65%, Ig2:23%, IgG3:6%, and IgG4:6%. Abnormal levels of one or more subclasses may be associated with autoimmune, anaphylatic and gut diseases, as well as with recurrent infection. Prepared from myeloma plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.
