title: Two-dimensional electrophoresis aided by personal computer analysis for screening of mutant proteins in inherited diseases.
abstract: A rapid and reproducible method of two-dimensional electrophoresis was developed for screening of abnormal proteins expressed in fibroblasts from patients with inherited diseases. After silver staining, the electrophoresis gel was subjected to semiautomatic digitizer-personal computer analysis: scanning with an image sensor video camera connected to a digitizer, followed by quantitative determination and statistical analysis with a personal computer. The protein spots analyzed by this method showed quantitative variations of various degrees, particularly in 2 of 247 spots examined. Seven spots were not always detected in control and pathological cells in this study. Slight variations in molecular weight were observed in 3 different spots.
