摘要
The Gallyas silver impregnation which is specific to neurofibrillary changes of paired helical filaments (PHF) and 15 nn straight filaments, was adapted to stain polypeptides separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Both PHF and tau polypeptides were readily and consistently stained by the Gallyas stain. This technique stained PHF > tau > high-molecular-weight microtubule-associated polypeptides (MAPS). Tubulin was stained only weakly. Neurofilament triplet, ubiquitin, bovine serum albumin and histones were unstained. The staining of PHF and tau polypeptides by Gallyas silver stain is consistent with the presence of tau in PHF.
