ES212010: 4-Nitrophenyl N,N-Diacetyl-β-D-Chitobioside Pack Size:25 mg N-(9-fluorenylmethoxycarbonyl)-O-(3C22H31N3O13 545. 49 A 4 nitrophenyl glycoside of N,N diacetylchitobiose (GlcNAc1 4GlcNAc), the conserved core disaccharide of N linked glycans. Used as a chromogenic substrate for chitinases, endo N acetylglucosaminidases (e. g., Endo H, Endo F), and N acetylhexosaminidases; enzymatic cleavage releases 4 nitrophenol. 4 Nitrophenyl (pNP) glycosides are chromogenic enzyme substrates: cleavage of the glycosidic bond by the target enzyme releases free 4
