The concentration of IgG subclasses was measured in matched pairs of maternal and cord serum by single radial immunodiffusion. IgG1, IgG3 and IgG4 were present in similar amounts in both the mothers and infants. IgG2 was present in the mothers at about 3 times the amount in the cord blood.
采用单向放射免疫扩散法对配对的母血和脐血血清中的IgG亚类浓度进行了测定。母亲和婴儿体内的IgG1、IgG3和IgG4含量相似。母亲体内IgG2的含量约为脐血中IgG2含量的3倍。
