Product details
U-Blot™ Ponceau S staining solution is negatively charged and binds to positively charged amino acid residues. It can also interact with the non-polar regions of proteins to form red bands. The detection limit of Ponceau S after polyacrylamide gel electrophoresis and transfer is 250 ng of protein.
Ponceau S staining is reversible and can be washed off with distilled water, PBS, or other suitable solutions.
Application
It is used for the detection of proteins on PVDF membranes, nitrocellulose membranes, and cellulose acetate membranes, but not suitable for the detection of nylon membranes.
Storage and stability：
Store in a sealed, dry place at room temperature and away from light. The shelf life is at least 1 year.
