Ponceau SPonceau S, Acid Red 112, or C.I. 27195 is a sodium salt of a diazo dye that may be used to prepare a stain for rapid reversible detection of protein bands on nitrocellulose or PVDF membranes (Western blotting), as well as on cellulose acetate membranes. A Ponceau S stain is easily reversed with water washes, facilitating subsequent immunological detection. Common stain formulations include 0.1% (w/v) Ponceau S in 5% acetic acid or 2% (w/v) Ponceau S in 30% TCA and 30% sulfosalicylic acid. Additional recommended knowledgeIts CAS number is [OC1=C(N=NC3=C C=C(N=NC4=CC=C (S(=O)(O)=O)C=C4) C=C3S(=O)(O)=O) C2=C(C=C(S(=O) (O)=O)C=C2)C=C1 S(=O)(O)=O. ] and its SMILES structure isSee also
