Our notes indicate that a 0.1% solution (1 mg/mL) in PBS or TBS can be stored for about a week at 0-4°C. For longer term storage, we would advise freezing the stock solution in aliquots.

General description
Subtilisin is a non-glycosylated single polypeptide chain without disulfide bonds and has a molecular weight of 27 KDa.
Application
This is a proteolytic enzyme isolated from the fermentation of Bacillus licheniformis. It is a serine endoproteinase with a broad specificity towards native and denatured proteins, and is active under alkaline conditions. Product P8038, also known as Subtilisin Carlsberg, has been used to hydrolyze cardiac cells to study the silencing of cardiac mitochondrial NHE1.
Biochem/physiol Actions
Subtilisin A is a member of the Serine S8 Endoproteinase family. It has broad specificity with a preference for a large uncharged residue in the P1 position. It hydrolyzes native and denatured proteins, and is active under alkaline conditions.
Proteinase catabolizes proteins by hydrolysis of peptide bonds. Proteases are inactivated by serine active-site inhibitors, such as phenylmethylsulfonyl fluoride (PMSF) and diisopropylfluorophosphate .
Analysis Note
Amino acid analysis and isoelectric focusing electrophoresis consistent with subtilisin Carlsberg.
Other Notes
One unit will hydrolyze casein to produce color equivalent to 1.0 μmole (181 μg) of tyrosine per min at pH 7.5 at 37 °C (color by Folin-Ciocalteu reagent).
