Physical State: Liquid
Purity and Specificity: Ponceau S Staining Solution contains Ponceau S in a specially formulated acetate buffer for optimal staining results. Ponceau S is a ready-to-use stain that can be used to quickly and reversible stain of proteins on blotting membranes after Western blot transfer. Staining of Nylon membranes is not recommended.
Background: Ponceau S Staining Solution is made using Ponceau S. Ponceau S is a sodium salt used for the detection of proteins on PVDF, and nitrocellulose membranes. Staining of blot transfer membranes permits visualization of proteins and allows the extent of transfer to be monitored. Ponceau S binds rapidly and reversibly to the positively charged amino groups and binds non-covalently to non-polar regions in the protein. Ponceau S stain is designed for rapid (5 min) staining on nitrocellulose or PVDF membranes and also for staining protein on cellulose acetate membranes. Microgram quantities of transferred protein will be detected as red protein bands with a clear background. Ponceau S staining on nitrocellulose and PVDF is reversible by washing the stained membrane with dH2O or blocking buffer, this allows further immunological detection.
