Ward's® Protein Fixative Stain

Highlights Protein Gels Safely, in 30 Minutes

Our stain images proteins electrophoresed on polyacrylamide gels and, because it’s vinegar based, it’s completely nontoxic. It will destain in water, 10% acetic acid, or white vinegar, eliminating the use of hazardous solutions. The 500 mL bottle stains up to 20 gels.
