Eco-friendly, ultra-sensitive colloidal coomassie G-250 stain.

ProtoBlue Safe

The Best Performing Colloidal Stain - Detects as little as 5ng protein

Compared to similar stains, the more finely controlled colloidal structure of ProtoBlue Safe improves both the sensitivity and the universality of staining. ProtoBlue Safe is less prone to high background caused by trace residual SDS in the gel.

Costs Less than Regular Coomassie

Laboratories typically spend twice as much per gel in the methanol and acetic acid for staining and destaining with regular Coomassie than for ProtoBlue Safe (including ethanol cost). In addition, ProtoBlue Safe is much faster, more sensitive, and you can pour the used stain solution down the drain. Protein visualization is faster, safer, more sensitive and less-expensive with ProtoBlue Safe.

Nonhazardous Disposal

Used stain solution is not a hazardous waste (as defined by United States Title 40 Code of Federal Regulations (40 CFR 261.24(a)).
