这里描述了五种主要的抗体。它们在大小和功能上差异很大。需要注意的一件事是表行“修复补体”，基本上，如果抗体能够修复补体，它就是将血清补体与抗体及其抗原相互作用的产物结合。这反过来又会导致进入宿主体内的微生物发生裂解，也可以称为细胞裂解。人体有许多防御抗原的系统。抗体是抗原防御的一个特别重要的分子。由于它们是专为个体化抗原而产生的特异性，以及它们的高亲和力，它们在体液亲和力中起着至关重要的作用。然而，它们的活动不仅与抗原结合有关，而且它们也是受体分子，反过来，促进一种反应，为免疫系统的其他效应功能招募免疫细胞。有各种各样的抗体可以分解成更小的子类;免疫球蛋白(Ig)A、IgD、IgE、IgG、IgM(表1)是五种主要的具有不同功能的抗体(表1)。在这类中还有另外四个IgG的子类，这些分子在它们的丰度上各不相同，各自的效应也各不相同。

Here is described the five major classes of antibodies. They vary greatly in size and function. One thing to note is the table line “fixes complement”, essentially if the antibody is able to fix it complements it is binding the serum complement to the product of the resulting interaction of the antibody and its antigen. This, in turn, can result in lysing of the microbes that have entered the host, can also be called cell lysing. The body has many defence systems against antigens. One especially important molecule to antigen defence is antibodies. Due to their specificity as a result of being created specifically for individualized antigens, and their high affinity of binding they play an essential role in humoral affinity. However, their activity is not only related to binding of antigens, but they also are receptor molecules and in turn, promote a response that recruits immune cells for other effector functions of the immune system. There are various classes of antibodies that break down into smaller subclasses; the five main classes with diverse functions are presented: immunoglobulin (Ig)A, IgD, IgE, IgG, and IgM (Table 1). Despite the various classes of antibodies a majority of them are IgG’s, they constitute approximately 75% of the serum immunoglobulin repertoire. Within this class there are another four subclasses of IgG’s, these molecules vary in their abundance and the respective effector effect each invokes.
