Boc leu arg arg amc

Manufactured by R&D Systems

Boc-Leu-Arg-Arg-AMC is a fluorogenic substrate used for the detection and quantification of trypsin-like serine proteases. It consists of the peptide sequence Boc-Leu-Arg-Arg coupled to the fluorescent reporter molecule 7-amino-4-methylcoumarin (AMC). Upon cleavage by a protease, the AMC moiety is released, resulting in an increase in fluorescence that can be measured.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
