ProtoBlue Safe Delivers Ultra-High Sensitivity Colloidal Coomassie Staining

The viability of eco-friendly colloidal coomassie staining has been limited by the fact that the technology has performed much better with custom buffer gels (MOPS, MES) than with standard Laemmli gels. National Diagnostics has developed a new stain formulation that works just as well with Tris-Glycine-SDS gels as with custom gels. And, furthermore, staining sensitivity has been improved for all gel types.
