摘　　要：作者采用琼脂糖凝胶高压电泳、PAGIEF及免疫固定技术测定了北京地区234份健康人(汉族)血清Bf的分布。其表型频率为SS171人,FS49人,FF8人,SS07 4人,FS07 1人及SS045 1人;基因频率为Bf^S=0.8462,Bf^F=0.1410,Bf^(S07)=0.0107,Bf^(S045)=0.0021。Bf表型分布与Hardy-Weinberg定律相吻合。经测定室温保存的已知Bf型的22份血痕,其可检出时限为3周。并将Bf型测定用于检案的血痕分析及亲权鉴定。The polymorphism of Bf was determinated in 234 healthy human sera in Beijing by agarose gel high-voltage electrophoresis and PAGIEF followed by immunofixation. The distribution of Bf phenotypes was observed: SS 171, FS 49, FF 8, SS07 4, FS07 1 and SS045 1. Their allele frequencies were, Bf^s = 0.8462, Bf^F=0.1410, Bf^(S07)=0.0107, Bf^(S045)=0.0021. The distribution of Bf phenotypes was good agreement with the Hardy-weinberg law.The time limits of Bf phenotypes in 22 bloodstain samples was determinated.
