Medchemexpress LLC m-PEG7-4-nitrophenyl carbonate | 678150-56-6 | >97.1% | C20H31NO11 | 2 MG
m-PEG7-4-nitrophenyl carbonate is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs consist of two distinct ligands connected by a linker, where one targets an E3 ubiquitin ligase and the other targets a specific protein. This mechanism leverages the intracellular ubiquitin-proteasome system for selective degradation of target proteins. It appears as a colorless to light yellow liquid and is intended for research use only.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Exploits the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
- Colorless to light yellow liquid appearance
- For research use only

Medchemexpress LLC 4-Nitrophenyl α-L-rhamnopyranoside | 18918-31-5 | >99.8% | 285.25 | 25 MG
4-Nitrophenyl α-L-rhamnopyranoside is a commonly used substrate in various biochemical assays to measure the activity of enzymes that hydrolyze rhamnose, such as α-L-rhamnosidase. It has unique chemical properties that allow it to be hydrolyzed by these enzymes to form a yellow product called p-nitrophenol. This makes it a useful tool for detecting and quantifying rhamnohydrolase activity in biological samples or microbial cultures.
- Used as a substrate in biochemical assays to measure α-L-rhamnosidase activity.
- Hydrolyzed to form a yellow product, p-nitrophenol, for detection and quantification.
- Useful for detecting and quantifying rhamnohydrolase activity in biological samples or microbial cultures.
- In vitro, it serves as a rhamnose-α substrate for rhamnosidase.
