Crystal Dyes

How can you be sure that your precious crystals are protein and not salt?

With the help of JBS Crystal Dyes you can discriminate between macromolecular crystals and salt crystals within minutes. Whatever suits your taste, you can stain your crystals blue, purple, green or red. All our crystal dyes are small molecules which are able to permeate the solvent channels of proteins and thus, staining them. In contrast, salt crystals will remain colorless.
