ClearBand Ponceau S is a ready to use solution for the rapid (5 min) and reversible detection of protein bands on nitrocellulose, PVDF, cellulose acetate and membranes. ClearBand Ponceau S rapidly stains proteins on membranes pink or light red. 
This staining solution is generally used to confirm protein transfer in Western blotting applications before probing with select antibodies.
ClearBand Ponceau S does not have a deleterious effect on the blotted polypeptides and can be completely removed from the membranes by repeated wash.
