Abstract
AbstractTwo rapid staining procedures using 8‐anilino‐1‐naphthalene sulphonate (ANS) and Nitro Blue Tetrazolium (NBT) were compared with a Coomassie Brilliant Blue R‐250 staining technique. The methods were applied to protein separations using both one‐ (1‐D) and two‐dimensional (2‐D) polyacrylamide gel electrophoresis. The ANS procedure worked well for both 1‐D and 2‐D gels. The NBT technique, although more rapid, gave satisfactory results only for 2‐D gels. The ANS and NBT staining methods were both compatible with Western blotting so that they could be used for visualisation of the separation profile prior to blot transfer to nitrocellulose.
