Ginkgolide B (BN-52021), a terpene lactone, is a potent platelet activating factor antagonist. Ginkgolide B protects endothelial cells via the activation of PXR from injuries induced by xeno- and endobiotics. Ginkgolide B can pass through the brain-blood barrier. Ginkgolide B has anti-oxidant, anti-inflammatory, anti-tumor, and anti-apoptotic activity. Ginkgolide B has marked neuroprotective effects against ischemia-induced impairments.

Description

In Vitro

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.
