What is Phenylmethylsulfonyl Fluoride?
Phenylmethylsulfonyl fluoride (PMSF) is an irreversible serine protease inhibitor, such as chymotrypsin, trypsin, thrombin, etc., the principle of action is to specifically recognize and sulfonate the active site of serine residues that determine enzyme activity. In addition, it has inhibitory effects on cysteine proteases (such as papain, whose inhibitory activity is reversed by DTT) and acetylcholinesterase of mammalian origin. PMSF is often added to the lysate before cell or tissue lysis to prevent protein degradation. PMSF can be used alone or in combination with other protease inhibitors such as aprotinin A or phosphatase inhibitors such as sodium orthovanadate.
This product is provided in powder form, it is insoluble in water, and its stability in aqueous solution is very poor, so it must be added to lysate or other aqueous solutions before use. PMSF powder can be dissolved in methanol, ethanol or isopropanol to prepare stock solution (such as 200 mM), and the effective working concentration is 0.1-1 mM.
Another non-toxic substitute for PMSF, AEBSF, is an irreversible serine protease inhibitor with the same activity and function as PMSF, and is easily soluble in water.
Phenylmethylsulfonyl Fluoride Uses

Typical Applications of Phenylmethylsulfonyl Fluoride (PMSF)
Lysis is a process that includes the breakdown of cell membrane layers and can facilitate comprehensive researches of mobile elements. The result of lysis is called lysate. The scientists studied PMSF as an inducer of enzymatic activity to stimulate wood deterioration (cherry timber chips) in fungal varieties (Daedaleopsis confragosa and also D. tricolor). This study demonstrates the essential function of PMSF in the bosom formula in the case of ligninolytic enzymes.
Phenylmethylsulfonyl fluoride can aid scientists prepare cell lysates accurately, ensuring that enzymatic reactions do not harm target healthy proteins via lysate buffer interactions. As an example, scientists commonly add PMSF to lysis buffers to prepare cell lysates from E. coli. The researchers used PMSF to the research of Sofalcone, a synthetic chalcone made use of as a protective agent for stomach mucus. The group included PMSF in the prep work of lysis barrier, cells extracts, tissue lysates, as well as cells nuclear essences. Making use of PMSF led the scientists to find the feature of the medicine in binding to the KEAP1 protein, causing an anti-colitis impact.
Phenylmethylsulfonyl fluoride is made use of to suspend details proteins after lysis to give soluble research study samples. The non-specificity of this inhibitor permits the researchers to use the substance to a selection of research studies. As an example, scientists made use of PMSF concentrations to examine the effects of anandamide in a computer mouse model that imitates cannabis activity. The researchers located that PMSF blocks the metabolic feature of anandamide, the main psychoactive ingredient in cannabis. PMSF offers scientists with access to compounds of passion.
In another instance, scientists took a look at aspects that contribute to the loss of microorganisms from preserved salt water examples. By adding PMSF to glutaraldehyde (the chemical made use of in the experiments), the scientists discovered that the loss of bacteria was lowered within 30-35 days. This experiment sustains the role of PMSF in preserving bacteria in glutaraldehyde-preserved samples.
Cellular degrees of biological healthy proteins are steady in their natural state or under mild ecological conditions. Artificial insemination researches and also experiments will certainly interrupt the cellular mechanics of healthy proteins, leading to destruction and denaturation. Protease inhibitors such as phenylmethylsulfonyl fluoride will maintain healthy proteins stable or cleansed during study by minimizing chemical reactions. Especially, during lysis, cells/organelles might deal with disturbance of regulative devices that usually hinder protease actions. This reaction causes the break down of numerous healthy proteins by proteolysis.
As a result, researchers might shed healthy proteins of interest in the process, which impacts the precision of their explorations. Scientists generally apply PMSF and AEBSF to healthy protein filtration processes since a lot of proteases in cells as well as tissues come from the team of serine proteases. Consequently, PMSF is an important element in the lysis barrier for serine-based experiments. The enhancement of PMSF decreases example contamination as a result of enzymatic reactions and also offers scientists with greater focus of practical proteins.
