The BLOT-FastStain from G-Biosciences is a stain designed for reversibly staining protein on nitrocellulose and PVDF transfer membranes. The product only stains protein and leaves the background white, resulting in high band visibility. The staining procedure takes 10 minutes and has a sensitivity of 2 ng BSA. Destain the membrane by simply rinsing in warm water for 10 minutes. After destaining, protein bands can be probed with Western blot protocols and other analyses including sequencing work.
