Ponceau S

Supplier: SIGMA ALDRICH MICROSCOPY

Ponceau S solution has been used for membrane staining (Western blotting).

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, ren

Supplier: Abcam

Protein dye for the rapid, reversible staining of protein bands on nitrocellulose, PVDF and cellulose acetate membranes. Staining is reversible allowing further i mMunological detection. Negative stain which binds to the positively charged amino groups of the protein. Also binds non-covalently to non-polar regions in the protein. (Note: Ponceau S is not suitable for use with nylon membranes.).

Supplier: Biotium

Ponceau S staining solution is used for the detection of proteins on PVDF and nitrocellulose membranes with a limit of detection of about 250 ng of transferred protein.

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 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.
