We have reexamined the detection of the components in a beta-mercaptoethanol and ammonium carbonate buffer extract of surface proteins of Candida albicans and the effects of postextraction manipulation of the extract on recovery of extract components. Following sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), preferential staining of some moieties was observed when bands detected by a commercial silver staining method or a Coomassie Brilliant Blue (CBB) staining method were compared. Additional protein bands that were either not detected or poorly detected by a single method alone were readily observed by a combined silver-CBB staining method. This method also detected alterations in the profile of extracted proteins from organisms grown in the presence of galactose or hemoglobin rather than glucose. Two-dimensional electrophoresis (2-DE) gel analysis by double stain showed better detection of several acidic and basic protein spots. Less than 10% of the extract as determined by a dye-binding assay was lost following either or both lyophilization and dialysis. These manipulations of the extract did not change the protein profile following SDS-PAGE as determined by the combined staining or Western blot analysis of a 70 kDa protein. These observations suggest that soluble cell wall proteins are not unusually sensitive to procedures routinely used in protein purification. In addition, these studies suggest that a modified staining method that combines both silver stain and CBB stain provides improved detection of cell wall proteins compared to either method alone.
