Descripciòn

SR-B-182 is a SARS-CoV-2 main protease (M_Pro) inhibitor with an IC₅₀ of 0.015 μM. SR-B-182 can be used for the research of COVID-19^[1].

In Vitro

SR-B-182 acts via a covalent mechanism based on nucleophilic aromatic substitution (SNAr), forming a covalent adduct with Cys145 at the catalytic site of MPro without causing steric hindrance conflict with the aa187-189 loop of MPro.^[1]

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
