EdmanSequencingofProteinsfrom2DGels
The Western blotting/sequencing technique using polyvinylidene difluoride (PVDF) membrane is one of the most popular technique for Edman sequencing. A protein sample is transferred from a 2D polyacrylamide gel electrophoresis (2D-PAGE) gel onto a PVDF membrane by electroblotting. The membrane carrying the protein is directly subjected to protein sequencing. If sequencing fails after a few cycles, the PVDF......阅读全文
