PageBlue Protein Staining Solution is a sensitive, economical formulation of colloidal coomassie G-250 dye for endpoint staining of proteins in polyacrylamide gels and on PVDF membranes without methanol or acetic acid.

• Easy-to-use—simply soak the gel in the ready-to-use solution and observe stained bands without destaining
• Staining time—25 to 40 minute protocol
• Safe—does not contain methanol or acetic acid
• Dynamic range—linear dynamic range of 5 to 500 ng
• Economical—can be reused up to three times

The simple PageBlue Protein Staining Solution protocol is sensitive, efficient, and eliminates the concern of over-staining gels, even after overnight staining. This protein stain delivers a dynamic range of 5 to 500 ng, which is approximately ten times more sensitive than traditional coomassie R-250-based dyes.
