With a superior signal-to-noise ratio and maximal sensitivity, pNP-Glc-Glc is a reliable and robust option for biochemical and biomedical research involving glucosidase enzymes.</p>

<p>4-Nitrophenyl 2-acetamido-3-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-alpha-D-galactopyranoside is a chromogenic substrate for alpha-galactosidase. Upon hydrolysis, para-nitrophenol is released yielding a yellowish colour. 4-Nitrophenyl 2-acetamido-3-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-alpha-D-galactopyranoside is used in different applications such as the Fabry disease diagnosis, glycolipid metabolism studies</p>
