Effect of acetic acid concentrations on protein staining intensity. Quantification of 4μg and 10μg of protein stained with 0.1% (w/v) Ponceau S with 1%, 10%, and 20% (v/v) acetic acid for 2 minutes. The lower blots show the same blots destained and then restained with commercial Ponceau S and the lower bar charts show the normalized results.
