mast cell degranulating peptide hr2

Mast Cell Degranulating Peptide HR-2 acetate from giant hornet Vespa orientalis that has biological effects similar to mast cell degranulating peptide from bee venom.

Immune cell migration-IN-2 is a potent inhibitor of immune cell migration, exhibiting an EC50 value of 13.5 nM in a T-cell adhesion assay. This compound is utilized in research pertaining to dry-eye and other retinal diseases [1]. As a click chemistry reagent, Immune cell migration-IN-2 possesses an alkyne group, enabling it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) with azide-containing molecules.

XT-2 peptide, an antimicrobial agent sourced from the skin secretions of Xenopus tropicalis, exhibits potent activity against E. coli, with a minimum inhibitory concentration (MIC) of 8 μM [1].
