| Popis: | A method for the direct visualization of Coomassie blue-stained polypeptide bands during electrophoresis with subsequent elution of polypeptides and removal of sodium dodecyl sulfate (SDS) and Coomassie blue is described. Primarily it is intended as a means for easy and—because there is no protein fixation step—nearly quantitative recovery of separated polypeptides for amino acid sequencing. It may also be used to obtain rapid information about the protein patterns during a run. Together with our new high resolution SDS-polyacrylamide gel electrophoresis system for small proteins and polypeptides (H. Schagger and G. Von Jagow (1987) , Anal. Biochem., 166, 368–379) the method described allows the preparative separation of protein fragments as even protein fragments between 1 and 3.5 kDa are easily detected. |
