title: Isoelectric focusing differences in the mobility of blood and semen PGM1 bands--the role of hemoglobin as a cause.
abstract: When using isoelectric focusing for the analysis of phosphoglucomutase isoenzymes, differences between the mobility of the first locus phosphoglucomutase (PGM1) bands have been noted in blood and semen samples from the same individual. This study was thus initiated to determine whether hemoglobin is responsible for these differences. Results revealed that the mobility of the PGM1 bands in diluted hemolysate and hemoglobin-removed hemolysate was similar to that seen in non-treated seminal plasma. Further, the mobility of PGM1 bands in hemoglobin-added seminal plasma was also similar to that seen in non-treated hemolysate. Additionally, on isoelectric focusing of the pI-markers, as well as non-treated hemolysate, hemoglobin-removed hemolysate, hemoglobin-added seminal plasma, and non-treated seminal plasma, distortions of iso-pH lines, i.e., "crank" formations were seen in the lanes of the non-treated hemolysate and hemoglobin-added seminal plasma. The above findings appear to indicate that differences in the mobility of PGM1 bands in the blood and semen result from the presence of high concentrations of hemoglobin in the analyzed samples.
