title: Isoelectrofocusing in the study of the BfF system: existence of two common subtypes of the BfF allele in a Japanese population.
abstract: The Bf gene frequencies including BfF' allele and BfF'' allele in a Japanese population were studied by using the PAGIF method. The results showed the Bf gene frequencies: BfF' allele = 0.0778, BfF'' allele = 0.1007 and BfS allele = 0.8215.
