C4-coated Ch(a+) red blood cells (RBC) were used as indicator cells in a serum inhibition reaction of anti-Ch(a), for the determination of the Ch group of serum. This serological study, combined with electrophoretic studies of C4 in a family material, showed that the C4M haplotype product was associated with partial inhibition of anti-Ch(a).
在抗-Ch(a)血清抑制反应中，将包被有C4的Ch(a+)红细胞用作指示细胞，以测定血清的Ch血型。这项血清学研究与对一个家系材料中C4的电泳研究相结合，表明C4M单倍型产物与抗-Ch(a)的部分抑制有关。
