0 Images
Cat. No.: HY-124324
CAS No.: 106927-48-4
Synonyms: p-Nitopheyl β-D-cellotioside
4-Nitrophenyl β-D-cellotrioside (p-Nitopheyl β-D-cellotioside) is a chromogenic substrate for endoglucanases and cellulose biohydrolases. As a fluorescent dye, nitrophenyl β-D-Cellotrioside can be hydrolyzed by enzymes to release 4-nitrophenol, producing a yellow color. The activity of the enzyme can be quantitatively analyzed by monitoring the change in absorbance at 405 nm .

Cat. No.: HY-138111
CAS No.: 129411-62-7
Synonyms: p-Nitopheyl β-D-cellotetaoside
4-Nitrophenyl β-D-cellotetraoside (p-Nitopheyl β-D-cellotetaoside) is a small molecule cellulose mimetic consisting of a tetramer of D-glucose units linked by β-1-4 glycosidic bonds. The fragmentation pattern of 4-Nitrophenyl β-D-cellotetraoside after enzymatic hydrolysis can be analyzed by TLC or by the release of 4-nitrophenol, which has a strong absorbance at 395 nm in alkaline solutions. 4-Nitrophenyl β-D-cellotetraoside can be used in cellulose degradation studies to determine the specificity of cellulases .
