An Agarose Gel Electrophoretic Method for Typing Phosphoglucomutase-1, Esterase D, or Glyoxalase I
A conventional agarose gel electrophoretic method was described for typing phosphoglucomutase-1, esterase D, or glyoxalase I as single systems. Bloodstain extracts were absorbed into 1-mm-thick agarose gels via an application mask. The electrode wick distance was 12 cm and electrophoresis was carried out at 400 V at 6°C. The electrophoretic run times were 30 min for glyoxalase and 1 h for esterase D or phosphoglucomutase. This method is reliable and produces highly resolved band patterns. Additionally, the shorter separation times as a result of the increased voltage gradient permitted typing of more samples in a given time period compared with presently used methods. This technique requires little technical expertise and can be incorporated into the laboratory at a minimal cost.
