Productdetails
Ponceau S (C.I. 27195) for histology and electrophoresis
Staining of NC membranes: 0.2-2 % Ponceau S in 3 % trichloroacetic acid (Art. No. 8789.1) + 3 % sulphosalicylic acid (Art. No. 4119.1), incubate for 1-5 mins. at room temperature. Enhance contrast by incubation in water acidified by a few drops acetic acid.
Staining of PVDF membranes: 0.1-1 % Ponceau S in 10 % acetic acid (Art. No. 6755.1), incubate 1-5 mins. at room temperature. Suitable for rapid control of transfer in Western blot, PVDF membrane should not be completely dried before immunodetection.
