title: Purification of a maize dehydrin.
abstract: A maize dehydrin with an apparent molecular weight of 20 kDa was purified from whole kernels of maize inbred line G50. Kernels were ground in a seed mill, stirred overnight in extraction buffer, and centrifuged to extract soluble proteins. The sample was heated to 89 degrees C and centrifuged to remove heat-insoluble proteins. The remaining soluble proteins were fractionated in a three-step chromatographic process. Following cation exchange, hydrophobic interaction, and gel filtration chromatography, pure dehydrin samples were obtained.
