Abstract
A much improved silver staining procedure for the detection of protein in polyacrylamide gels of 0.8-3.0 mm thickness is described. It achieves very high sensitivity (detecting less than 0.01 ng bovine serum albumin/mm2) by overstaining and subsequently removing nonspecific background stain using a modified, reliable destaining procedure. Maximum sensitivity follows prediamine equilibration in 0.1% (w/v) formaldehyde solution. With two-dimensional electrophoresis the improved staining procedure reveals greater than 200 polypeptides in unconcentrated human urine and greater than 150 polypeptides in a single human fingerprint.Entities:
