Wighteone (6-Isopentenylgenistein; Erythrinin B) is a prenylated isoflavone that acts as a HSP90/EGFR^L858R/T790M inhibitor and antifungal agent. Wighteone reduces the expression level of HSP90, blocks EGF-induced phosphorylation of EGFR, and thereby inhibits the downstream ERK and AKT signaling pathways. Wighteone induces cell cycle redistribution, inhibits proliferation and triggers apoptosis in cancer cells. Wighteone can be isolated from Erythrina suberosa, and can also be induced to synthesize in Lotus japonicus under specific conditions. Wighteone can be used to study HER2-positive breast cancer, leukemia, non-small cell lung cancer with EGFR^L858R/T790M mutation, and fungal infections.

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.
