Determination of phosphoglucomutase phenotypes in hair bulbs.

The research was to determine a simple method of phosphoglucomutase phenotype identification in hair bulb. The agarose technique and electrophoresis on cellulose-acetate foil methods were chosen because a small quantity of the maternal available for examination. It was found out that 1 or 2 bulbs are sufficient to identify the PGM1 features if the electrophoresis method is applied and if more bulbs are available, the PGM3 characteristic can also be identified. The modified technique was used for staining the phosphoglucomutase phenotypes.
