Application
Ponceau S stain comes ready-to-use and is designed for rapid (5 min) staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes. Ponceau S staining on nitrocellulose and PVDF is reversible by washing the stained membrane with 0.1 M NaOH for 1 min. The stained and destained membrane can then be immunologically detected (Western blotting). A product information sheet is supplied which includes the staining procedure for cellulose acetate, nitrocellulose, and PVDF.
