BTA-188

Customer Review

Based on 1 Customer Validation

BTA-188, a pyridazinyl oxime ether, is an orally active, potent inhibitor of rhinoviruses (HRV) and enterovirus (EV) 71 in vitro. BTA-188 inhibits HRV-2 replication with an IC₅₀ of 0.8 nM and an IC₉₀ of 11 nM. BTA-188 inhibits enterovirus with an IC₅₀ of 82 and an IC₉₀ of 109 nM. BTA-188 is a potential chemotherapeutic agent for infections caused by the viruses in the Picornaviridae.

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.
