<p>Chromogenic substrate targeting the beta-galactosidase enzyme</p>

<p>N-α-benzoyl-DL-arginine-4-nitroanilide hydrochloride is commonly used as a substrate in various enzymatic assays, particularly for studying proteases like trypsin and chymotrypsin. It serves as a synthetic substrate to measure the activity of these enzymes. For instance, it has been used to determine trypsin activity in different organisms and tissues. The substrate has also been employed in studying the enzymatic properties of various proteases, including those found in latex, snake venoms,  and plant seeds. Additionally, it has been utilized to assess the effects of different compounds on trypsin activity, such as condensed tannins and wine.</p>

<p>5-bromo-3-indolyl-b-d-glucopyranoside, also known as 5BIG, is an enzyme substrate for beta-glucosidase. It is used in bacterial assays for the identifcation of Gram-positive bacteria such as Staphylococcus aureus and Bacillus subtilis. After cleavege, it gives an intense blue color.</p>

<p>Aldol® 467 N-acetyl-beta-D-glucosaminide is a chromogenic and fluorogenic enzyme substrate used for detection of ?-N-acetyl-glucosaminidase activity. The colorless enzyme substrate is cleaved in the presence of ?-N-acetyl-glucosaminidase yielding development of a yellow product. In addition, green fluorescence is generated when a suitable matrix or Aldol® 355 fluorescence enhancer is present. Aldol® 467 N-acetyl-beta-D-glucosaminide amide can be used in enzymatic assays or in live bacterial cultures. Aldol® 467 N-acetyl-beta-D-glucosaminide is suitable for use in liquid and solid media, under aerobic as well as anaerobic conditions.</p>

<p>4-Nitrophenyl 2-acetamido-6-O-(2-acetamido-2-deoxy-b-D-glucopyranosyl)-2-deoxy-a-D-galactopyranoside is a chromogenic pNP glycoside substrate designed for the detection and assay of specific enzymes, particularly glycosidases. Upon enzymatic hydrolysis, this substrate releases a quantifiable 4-nitrophenol moiety enabling straightforward colorimetric measurement. This pNP-linked substrate is versatile and can be efficiently employed in enzyme activity assays, screening enzyme inhibitors, and assessing enzyme mechanisms, enhancing research and development processes in the field of glycobiology.</p>
