WebUnder normal assay conditions that involve comparatively high molar protein/dye ratios the dye binds almost exclusively to arginine and lysine residues ( 4 ). The dye does not bind to free arginine or lysine, nor to pep-tides smaller than about 3000 Da ( 3, 12 ). WebDye-Binding Methods. Dye-binding methods are based on the quantitative reaction between ionized groups of proteins and ionized groups of the dye, i.e., sulfonic acid. The amido black method which uses CI Acid Black I, is routinely used in different countries.

WebThis chapter discusses dye-binding methods. The earliest evidence for the interaction of dyes with proteins was the observation of indicator errors in protein solutions. It has also long been known that acidic and basic dyes are effective protein precipitants. WebHowever, among the disadvantages of the method is its variability of color development with different proteins: the absorbance change per unit mass of proteins varies with the type of the protein. On binding to a protein, the negatively charged Coomassie brilliant blue G-250 dye molecule will give an overall negative charge to the protein.
