2-Nitrophenyl butyrate is a chromogenic enzyme substrate that is commonly used in enzymatic assays to detect lipases and esterases. When hydrolyzed by these enzymes, the substrate yields a yellow product that can be detected spectrophotometrically at 405 nm. The advantage of using 2-nitrophenyl butyrate is its high sensitivity and specificity for detecting lipolytic and esterolytic activities. This substrate is widely used in various applications, including enzyme kinetics studies, inhibitor screening, and the determination of esterase activity in biological samples such as serum, plasma, and cell lysates.

4-nitrophenyl 2-acetamido-3-O-[2-O-(2,3,4-tri-O-benzoyl-a-L-fucopyranosyl)-3,4,6-tri-O-acetyl -D -galactopyranosyl]-2 deoxy 6 O trityl b D glucopyranoside is a chemiluminescent substrate that can be used in biochemical assays. It reacts with oxygen to produce light when it is excited by a UV or blue light source. This product has been tested for purity and quality by HPLC analysis and spectroscopy.
