Medchemexpress LLC 4-Nitrophenyl α-L-rhamnopyranoside | 18918-31-5 | 99.8% | 285.25 | 50 MG
4-Nitrophenyl α-L-rhamnopyranoside is a substrate commonly used in various biochemical assays to measure the activity of enzymes that hydrolyze rhamnose, such as α-L-rhamnosidase. It possesses unique chemical properties that enable its hydrolysis by these enzymes, resulting in the formation of a yellow product called p-nitrophenol. This characteristic makes it a valuable tool for detecting and quantifying rhamnohydrolase activity in biological samples or microbial cultures.

Medchemexpress LLC 4-Methylumbelliferyl sulfate potassium | 15220-11-8 | 99.3% | 294.32 | 500 MG
4-Methylumbelliferyl sulfate (potassium) is a fluorescent substrate used to detect sulfatase activity in biochemical and biomedical research. It consists of a sulfate group attached to a fluorescent molecule, which is cleaved by sulfatase enzymes. Upon cleavage, it releases a highly fluorescent product detectable by fluorescence microscopy or spectroscopy. This allows for accurate detection and quantification of these enzymes in various biological samples. It is for research use only and not sold to patients.
