Analysis of soluble proteins in natural Cordyceps sinensis from different producing areas by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and two-dimensional electrophoresis

As one of the bioactive components in Cordyceps sinensis (CS), proteins were rarely used as index components to study the correlation between the protein components and producing areas of natural CS.Protein components of 26 natural CS samples produced in Qinghai, Tibet, and Sichuan provinces were analyzed and compared to investigate the relationship among 26 different producing areas.Proteins from 26 different producing areas were extracted by...
