| Application | R-PROB is a unique protein detection system designed for staining of proteins on nylon, nitrocellulose, and PVDF membranes or PAGE gels with the detection sensitivity similar to that of Coomassie stains. Most other stains produce high backgrounds on nylon membranes due to strong charge interactions with the membrane. The mixing of equal amounts of Solution A and B activates the stain, which produces lavender stained protein bands. The staining is easily reversible with an EDTA solution so that the blot can be reused for Western blotting or for amino acid sequence analysis (PVDF). R-PROB does not contain the toxic chemicals cacodylic acid or potassium ferrocyanide. |
