Immune Signaling

Reference compounds for inflammatory-signaling and thiol-redox research: KPV, the C-terminal tripeptide of α-MSH, and reduced glutathione (GSH). Like everything in the catalog, each lot is tested by a third-party laboratory and its signed certificate published; a compound on pre-order ships only once its first lot's certificate is published.
