Vicilin and legumin storage proteins are plentiful in water and alkali soluble protein fractions of glandless cottonseed On this work, we sequentially extracted water (CSPw)- and alkali (CSPa)-soluble protein fractions from glandless cottonseed. SDS-Gel electrophoresis separated CSPw and CSPa to eight and 14 dominant polypeptide bands (110-10 kDa), respectively. Liquid chromatography-electrospray ionization-tandem mass spectrometry recognized peptide fragments from 336 […]
