Description

During routine protein electrophoresis workflows, researchers often need a reliable method to quickly visualize protein bands after SDS-PAGE or Native PAGE without spending additional time on complicated staining and destaining procedures. Traditional Coomassie protein gel staining workflows may require multiple steps, including fixation and destaining, which can delay protein analysis and downstream decision-making.

Coomassie Brilliant Blue Rapid Staining Solution (No Destaining Required) is a ready-to-use protein gel staining solution designed for rapid visualization of protein bands in polyacrylamide gels. This rapid Coomassie stain enables room-temperature staining without traditional destaining steps, providing a convenient solution for SDS-PAGE protein staining, Native PAGE staining, and routine protein analysis workflows.

RP0271 provides fast protein gel visualization with visible bands within approximately 2 minutes and can detect protein bands at approximately 10 ng sensitivity. The methanol-free and acetic acid-free formulation offers a more convenient and environmentally friendly alternative for routine protein electrophoresis applications.

This Coomassie Brilliant Blue staining solution is suitable for researchers performing protein purification monitoring, recombinant protein analysis, electrophoresis quality control, and mass spectrometry-compatible protein visualization workflows.

Protocol Overview

For routine protein gel staining, the electrophoresed PAGE gel is directly immersed in sufficient Coomassie Brilliant Blue Rapid Staining Solution to completely cover the gel.

Remove the PAGE gel after electrophoresis and place it into a suitable staining container.
Add enough staining solution to cover the gel surface.
Incubate with gentle shaking. Protein bands begin to appear within approximately 1–2 minutes.
Continue staining according to experimental requirements. Longer staining times may improve band intensity.
After staining, the gel can be transferred into water for storage and imaging.

For a standard 8 × 10 cm gel with 0.75 mm thickness, approximately 30–50 mL staining solution is typically sufficient. Larger or thicker gels may require additional staining solution and longer staining time.
