## Overview

Coomassie Brilliant Blue G-250 Protein Stain is a ready-to-use, high-sensitivity staining solution designed for rapid and clear visualization of protein bands in various electrophoresis gels. Manufactured in the USA under stringent GMP standards, it detects protein quantities as low as 8 ng per band within 60-90 minutes, eliminating the need for de-staining and ensuring reliable, reproducible results for advanced protein analysis.

## Description

Polyacrylamide gel electrophoresis is one of the most widely used methods to analyze proteins and after separation by electrophoresis, protein bands need to be detected with a suitable protein stain. Our Coomassie Brilliant Blue G-250 Protein Stain is a ready to use protein staining solution. The Coomassie G-250 dye binds to proteins through ionic interactions between the sulfonic acid groups of the dye and positive protein amine groups and through Van der Waals attractions. The capability of G-250 to create a rapid and convenient staining procedure is due to its particular properties and manifests a leuco form below pH 2. Solutions of the dye, dark blue black at pH 7, turn a clear tan upon acidification. The leuco form recovers its blue color upon binding to protein, apparently due to the more neutral pH of the environment around the protein molecule. Under ideal staining conditions, a gel placed in Coomassie Brilliant Blue G-250 Stain will manifest blue protein bands on a light amber background. The protein bands develop rapidly and there is no need to de-stain, as the background color is not dark. Our stain can be used with SDS-PAGE, Native PAGE, Tricine gels with fixation step, 2-D Electrophoresis, etc. It stains the proteins with high band visibility and the protein bands up to 0.1 µg protein can be observed within 5 minutes, while staining the gel. The sensitivity of our Coomassie Brilliant Blue G?250 Protein Stain is up to 8 ng protein/ band, as observed in 4?20% SDS-PAGE gel loaded with BSA. Features: Ready to use solution Fast protein staining ? in about 60-90 minutes Detects up to 8 ng protein per band Protein bands appear and visible while the gel in stain Compatible with fixing by alcohol Mass Spec compatible
