In a method for determining macromolecules in polyacrylamide gels comprising the steps of forming a latent stain image by nucleating the macromolecules in the gel with a palladium tetramine salt and developing the latent stain image by treating the gel with a physical developing solution comprising dimethylamine borane and a transition metal salt, the improvement comprises contacting the developed latent stain image with a 1-phenyl-2-tetrazoline-5-thione or a salt of 1-phenyl-1H-tetrazole-5-thiol.
