Product Description

Overview

Ponceau S staining solution can be used for rapid detection of proteins on PVDF membrane, nitrocellulose membrane (NC membrane) and cellulose acetate membrane. The principle is that Ponceau S staining is negatively charged and can combine with positively charged amino acid residues. Meanwhile, Ponceau S staining can also combine with the non-polar region of the protein to form red bands. The protein staining is reversible and can be washed with distilled water, PBS or other appropriate solutions after staining.

The main ingredient of this product is 0.2% Ponceau S staining.
