The polymorphism of properdin factor B (Bf, C3 proactivator) in a population sample from Hessen, Germany has been investigated by agarose gel electrophoresis and immunofixation. In 522 unrelated individuals seven different phenotypes were observed and the following allele frequencies calculated: BfS

โฆ Synopsis
Properdin factor B phenotypes were determined in 7 Bantu speaking Negroid populations, 1 Indian, and 1 Colored population of South Africa in a total of 1258 individuals. In the Negroid populations allele frequencies were: BfF 0.655, BfS 0.282, BfRARE 0.063, in the Indian population: BfF 0.322, BfS 0.645, BfRARE 0.033, and in the Colored population: BfF 0.513, BfS 0.435, BfRARE 0.052. In addition, 2 so far unknown F alleles and possibly 1 new S allele were discovered.
