[Improvement of two-dimensional gel electrophoresis of total proteins from rice anthers].
This paper reported an improvement in 2-D gel electrophoresis of the proteome in Honglian cytoplasmic male sterile rice. An IPGphor unit with immobile pH gradient strips was used as the first dimension and SDS-PAGE as the second. The total anther proteins were extracted using TCA/acetone and then were washed 5-6 times with acetone till the proteins were white and clean, and then tributylphosphine and DTT were added into the rehydration buffer to improve the solubility of the proteins. The 2-D gel was stained by both methods of coomassie blue G-250 and silver. Extraction of proteins, pH of the strips and rehydration of the strips were optimized and compared. Higher repeatability and better separating protein pattern could be gained by this technique.
