Water-soluble, substrate for sortase mediated labeling of proteins. Sortase catalyzes a transpeptidase reaction between a specific internal sequence of a protein and an amine group present on the N-terminus of triglycine recently has become an area of great interest. This method of labeling proteins has been denoted as “Sortagging”.
APDye™ 488 Gly-Gly-Gly is a water-soluble, pH-insensitive from pH 4 to pH 10, green-fluorescent probe. Its excitation ideally suited for the 488 nm laser lines. APDye™ 488 is structurally identical to Alexa Fluor® 488.
