Pig Aprotinin, Active Protein, Cat#RPU60527
SDS-PAGE
Aprotinin (AP) is a competitive serine protease inhibitor. Reversibly binds to and blocks the enzymatic active site. Inhibits a range of serine proteases including trypsin, chymotrypsin, kallikrein and plasmin. Inhibits cytopathogenic effect of SARS-CoV-2 and double-stranded RNA formation in SARS-CoV-2-infected cells. The activity of recombinant pig AP was measured by its ability to inhibit trypsin cleavage of a peptide substrate BAPNA in the assay buffer 200 mM Triethanolamine hydrochloride, 20 mM CaCl2, pH 7.8. The reaction was performed in adding 20 μl 4 mg/mL trypsin diluted by 1mM HCl to 160 μl assay buffer and 20 ul 0.85% (w/v) NaCl and start the reaction by adding 100 ul of 1mg/ml BAPNA. Include a substrate blank containing 160 μl assay buffer, 20 μl 1mM HCl, 20 ul 0.85% (w/v) NaCl and 100 uL of 1mg/ml substrate. Rapidly mixing at 25 °C, then read at 405 nm in kinetic mode for 5 minutes using a microplate reader controlling the ∆A405nm/min=0.08-0.12. The 20 ul different concentrations of recombinant pig AP was incubated with 20 ul 4 mg/mL trypsin in 160 ul assay buffer at 25°C for 10 minutes followed by adding 100 ul substrate, then read at 405 nm in kinetic mode for 5 minutes using a microplate reader. Under these conditions, the enzyme amount of 50% inhibition of trypsin activity per minute is defined as a unit. The specific activity of recombinant pig AP is >9000 U/mg.

Let customers speak for us

from 218 reviews

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
