Subtilisin
Based on 1 Customer Validation
Subtilisin (EC 3.4.21.14) is a bacterial serine protease. Subtilisin induces Apoptosis. Subtilisin stimulates the expression of pro-allergic cytokines (IL-1α, IL-33). Subtilisin induces prototypic allergic lung inflammation. Subtilisin exhibits anticancer activity against breast and colon cancer. Subtilisin shows antifouling activity. Subtilisin can be used as a detergent additive.

Biological Activity
Product Information
It is a proteolytic enzyme made by deep fermentation, extraction and purification of Bacillus subtilis selected by protoplast mutagenesis method. It can hydrolyze the peptide chain of protein molecules to generate polypeptides or amino acids. It can also catalyze the synthesis of polypeptides in organic solvents. This product contains stabilizers.
Effective temperature range: 20-60°C, the optimum temperature is between 35-45°C.
Effective pH range: 6.0-11.0, the optimum pH range is between 9.5-10.5.
Activators: Ca2+, Mg2+, Mn2+, Zn2+, Fe2+.
Inhibitors: Reagents acting on serine such as sulfonyl halides.
Instructions
Soluble in 100 mg/mL ddH2O, avoid repeated freezing and thawing, or dissolve according to specific experimental references.
Subtilisin (3-5 μg/mL; 24 h) shows cytotoxic effects in MCF-7 and HT-29 cancer cells, with MCF-7 cells showing apoptotic cell characteristics and HT-29 cells showing necrotic cell characteristics[1].
Subtilisin shows antifouling activity[2].
Subtilisin (1.0-10 μg/mL; 3-6 h) stimulates the expression of pro-allergic cytokines IL-1α, IL-33, TSLP, and the growth factor amphiregulin in H292 cells[4].

-
Animal Model:Female C57BL/6 mice (8-12 weeks old), allergic airway disease model[4]
-
Dosage:1 μg
-
Administration:Subcutaneous (s.c.) or intranasal (i.n.). Sensitization: s.c. or i.n. injection with 1 μg of subtilisin on days 0 and 7. Challenge: i.n. administration with 1 μg of subtilisin on days 14 and 21. whole experimental cycle of 22 days
-
Result:Induced high levels of serum IgE and specific IgG1.
Led to intense airway eosinophilic inflammation, as shown by total and differential cell counts in bronchoalveolar lavage (BAL).
Induced pronounced airway inflammation and mucus formation.
Promoted increased bronchoconstriction to inhaled methacholine and induced a late-phase response.
Induced allergic responses dependent on its protease activity, protease-activated receptor (PAR)-2, IL-33 receptor ST2, and MyD88 signaling.
