PMSF (Phenylmethylsulfonyl fluoride) is a widely used protease inhibitor that helps prevent protein degradation during biochemical and cell biology experiments. This 25g quantity is suitable for large-scale applications in protein isolation, purification, and proteomics research. PMSF specifically targets and inhibits serine and cysteine proteases, which are responsible for breaking down proteins during sample processing. By inhibiting these enzymes, PMSF preserves the integrity of proteins, allowing researchers to study their structure, activity, and interactions. It is a critical reagent in enzyme assays, protein purification, and cellular protein analysis, ensuring the accuracy and reliability of experimental results.
