Structural variation in the second component of human complement was identified in about 4% of serum samples from random unrelated individuals of all the major races. Three forms of C2 have been identified by isoelectric focusing in polyacrylamide gel and development of patterns in agarose gel containing antibody-sensitized sheep red cells and C2-deficient serum: C2 C (common), C2 A (acidic), and C2 B (basic). The C2 variants were shown to be inherited as autosomal codominant traits, and suggestive evidence for close linkage between C2 and Bf was obtained.
在所有主要种族的随机无关个体的约4%血清样本中,发现了人类补体第二成分的结构变异。通过在聚丙烯酰胺凝胶中进行等电聚焦,并在含有抗体致敏绵羊红细胞和C2缺陷血清的琼脂糖凝胶中显影图谱,已鉴定出三种形式的C2:C2 C(常见型)、C2 A(酸性型)和C2 B(碱性型)。C2变体显示为常染色体共显性性状遗传,并获得了C2与Bf紧密连锁的提示性证据。
