Electropherogram pattern similarity of seed proteins from 21 different soybean (Glycine max) varieties

Abstract

Soybean (Glycine max) seed protein has been characterized using a phosphate-detergent (sodium dodecyl sulfate) polyacrylamide gel electrophoretic system, which has been extensively tested on plant proteins. The same general densitometer electropherogram pattern as regards numbers and kinds of protein components resolved was observed for all soybean varieties tested, and one pattern is presented along with appropriate descriptive characterizations (numbers, molecular weights, relative mobility, and light absorption at 597 nm) to aid in distinguishing the components. Quantitative differences, however, of individual components may occur.
