C6 reference typing report.

Various C6 protein allotypes were examined using polyacrylamide gel isoelectric focusing followed by immunoblotting or hemolytic overlay. For several 'difficult' allotypes, neuraminidase treatment of samples and long-distance isoelectric focusing gels were applied. Nineteen different allotypes were distinguished besides the two common allotypes C6 A and C6 B. They were designated basically according to the previous statement on C6 nomenclature [Mauff et al., 1980].

[The polymorphism of human erythrocytic esterase D. Phenotype distribution and gene frequency in Northern Germany (Schleswig-Holstein); description of an Es D 4 family (author's transl)].

A good correlation between the actual phenotype distribution of esterase D and the expected distribution was found in the analysis of a random sample of 2028 unrelated persons, 54 umbilical cord blood samples, 406 mother/child comparisons, 24 family investigations, one fraternal and 32 identical twin investigations. The assume gene frequencies in Northern Germany were calculated for Es D1 =0.8935 and Es D2 =0.1065 for an aggregate sampling. Gene defects were not observed, and one family exhibited the variant Es D4 in the father (Es D 4--1) and son (Es D 4--2). Likewise, these phenotypes distinctly distinguish themselves by electrofocusing from the phenotypes Es D 1, Es D 2--1, and Es D 2.
