Abstract

A method is described for the production of rabbit anti-Gm sera using normal IgG proteins and fragments thereof as the immunogens. Anti-G3m(16) and anti-G3m(21) were readily producible by immunizations with protein A-purified IgG3 proteins of G3m(13, 15, 16) and G3m(21) type, respectively. Anti-G1m(2), anti-G1m(3), and anti-G3m(5) were obtained by immunizations with type Gm(1, 2, 21) Fc fragments, type Gm(1, 3, 5, 13) IgG1-rich IgG, and type G3m(5, 13, 21) IgG3, respectively. These immune sera can distinguish the 9 Gm phenotypes in the Japanese.

摘要

描述了一种使用正常IgG蛋白及其片段作为免疫原生产兔抗Gm血清的方法。分别用G3m(13, 15, 16)型和G3m(21)型的蛋白A纯化的IgG3蛋白免疫,可轻易产生抗G3m(16)和抗G3m(21)。分别用Gm(1, 2, 21) Fc片段、富含Gm(1, 3, 5, 13) IgG1的IgG和G3m(5, 13, 21) IgG3免疫,可获得抗G1m(2)、抗G1m(3)和抗G3m(5)。这些免疫血清可区分日本人的9种Gm表型。
