Ponceau S 75% (dye content), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Ponceau S (C.l. 27195) is an anionic, very hydrophilic disazo dye. It is also known as fast ponceau 2B. Ponceau S is widely used to stain proteins on gel electropherograms. It is a suitable stain for proteins adsorbed onto nitrocellulose membranes. It also has applications in botanical staining manuals as a stain for sieve plate elements.

Ponceau S, Bioreagent for electrophoresis, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Ponceau S is the sodium salt of a diazo dye. It is used to make a stain for rapid reversible staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes. The stain is reversed with water washes and aids in subsequent immunological detection. The following are two common stain formulations: 0.1% Ponceau S (w/v) in 5% acetic acid 2% Ponceau S (w/v) in 30% TCA, 30% sulfosalicylic acid.

Ponceau S is a rapid and reversible stain for detecting protein bands on Western blot membranes and can be used with PVDF, nitrocellulose and cellulose acetate membranes*. Ponceau S is a negative stain, which binds to the positively charged amino groups of the protein and it also binds non‐covalently to non‐polar regions in the protein.
