Quorum sensing-IN-9

Quorum sensing-IN-9 (Compound 7d) inhibits quorum sensing in Pseudomonas aeruginosa by binding PqsR proteins. Quorum sensing-IN-9 inhibits the expression of quorum sensing systems related genes lasB, rhlA and pqsA, blocks the generation of virulence factors elastase, pyocyanin and rhamnolipid. Quorum sensing-IN-9 destorys the motility of P. aeruginosa, inhibits the biofilm formation, decreasing the virulence and pathogenicity of P. aeruginosa. Quorum sensing-IN-9 exhibits anti-infectious activity in Galleria mellonella larval model.

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.
