The esterase D polymorphism as revealed by isoelectric focusing in ultra-thin polyacrylamide gels

The polymorphism of human red cell esterase D (EsD) was studied using isoelectric focusing (pH 4-6) in ultra-thin polyacrylamide gels. Typing was possible without the EsD isozymes attaining true equilibrium focusing conditions. Using this single method, six phenotypes (EsD 1, 2-1, 2, 5-1, 5-2 and 5) could be recognized in the White population of south-east England. Family studies showed these to be controlled by three co-dominant alleles and the gene frequencies were calculated to be EsD1 0.8856; EsD2 0.0946 and EsD5 0.0198. For successful and reliable EsD typing by this method, the electrophoretic system must be carefully optimized with respect to the duration of electrophoresis and the temperature attained in the gel during the electrophoretic run.     

Red cell phosphoglucomutase (PGM1) subtypes in Egyptians

The polymorphism of the human red cell phosphoglucomutase 1 (PGM1) in samples from Egyptians (n = 134) was investigated using isoelectric focusing in thin-layer polyacrylamide gel. In the studied population samples nine common phenotypes were observed, and the calculated frequencies for the genes PGM1+1, PGM1-1, PGM2+1 and PGM2-1 were 0.6381, 0.0821, 0.2201 and 0.0597, respectively. The observed and expected phenotypes provide a good fit to Hardy-Weinberg equilibrium. The four alleles system will increase the probability of excluding a man falsely accused of paternity to 30% as compared with 16% if the two alleles system is used.

Phosphoglucomutase (PGM1) subtypes in South Polish population were examined by thin-layer polyacrylamide gel isoelectrofocusing (pH 5-7) using fresh hemolysates from 460 unrelated adults. The allele frequencies in Polish population are as follows: PGM1+1 = 0.6402, PGM1-1 = 0.1185, PGM2+1 = 0.1880, PGM2-1 = 0.0533.     

Genetic study of red cell esterase D polymorphism by ultrathin layer isoelectric focusing. Distribution in the Veneto population (Italy)

Human red cell Esterase D (EsD) was analyzed by isoelectric focusing (IEF) on ultrathin-layer polyacrylamide gel with a pH range of 5.0-6.0. Hemolysates were treated with Dithiothreitol to avoid loss of activity and change of the isozyme patterns by in vitro storage effects. In our sample of 951 unrelated persons from Veneto, seven different phenotypes were observed. The following allele frequencies were calculated: EsD1 = 0.8476, EsD2 = 0.1336, EsD5 = 0.0178, and EsDV = 0.0010.
