Phenylmethanesulfonyl fluoride pmsf

Manufactured by Wuhan Servicebio Technology
Sourced in China

Phenylmethanesulfonyl fluoride (PMSF) is a serine protease inhibitor commonly used in molecular biology and biochemistry applications. It functions by irreversibly inhibiting the activity of serine proteases, enzymes that cleave peptide bonds. PMSF is often utilized in the preservation and stabilization of protein samples during extraction and purification processes.

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.
