    Product Description

    Cyclosporin H is a natural cyclic undecapeptide that selectively antagonizes the formyl peptide receptor at concentrations ranging from 0.1 to 10 µM.1,2,3 Unlike cyclosporin A (Item No. 12088), cyclosporin H does not bind cyclophilin to evoke an immunosuppressant response.4 Cyclosporin H has been reported to inhibit phorbol ester-mediated effects in mouse skin and block calcium/calmodulin-dependent EF-2 phosphorylation in vitro.5

    WARNING This product is not for human or veterinary use.
