Usnic acid (Standard)

Usnic acid is a secondary metabolite of lichens with a unique dibenzofuran skeleton. Usnic acid inhibits DNA/RNA synthesis and has antibacterial activity. Usnic acid induces cell cycle arrest and apoptosis and has anticancer activity. Usnic acid inhibits RANKL-mediated osteoclast formation and function by reducing the transcriptional and translational expression of NFATc1. Usnic acid has antioxidant and anti-inflammatory activities by inhibiting lipid peroxidation and myeloperoxidase.

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.
