| Description | PAR-4 (1-6) amide human is an N-terminal fragment of protease-activated receptor 4 (PAR4). PAR-4 (1-6) amide human induce platelet aggregation[1] | Adrenocorticotropic Hormone (ACTH) (1-39), human is a melanocortin receptor agonist | Apo-Bovine Transferrin refers to iron free Transferrin (HY-P3267), serves as Transferrin receptor ligand and mediates iron release from endothelial cells. Apo-Transferrin indicates an iron deficient environment, can directly bind to hephaestin, which can convert Fe2+ to Fe3+. Apo-Transferrin Apo-Bovine Transferrin refers to iron free Transferrin (HY-P3267), serves as Transferrin receptor ligand and mediates iron release from endothelial cells. Apo-Transferrin indicates an iron deficient environment, can directly bind to hephaestin, which can convert Fe2+ to Fe3+. Apo-Transferrin mediates iron efflux most likely in cooperation with ferroportin 1[1]... Read More | Bradykinin is an effective endothelium-dependent vasodilator that can lower blood pressure. Bradykinin can induce contraction of bronchial and intestinal non-vascular smooth muscle, increase vascular permeability, and participate in the mechanism of pain[1][2][3][4][5] | STh, an Escherichia coli heat-stable toxin, is a 19 amino acid polypeptide encompassing three disulfide bridges. STh is an antigen of interest in the search for a broad coverage enterotoxigenic Escherichia coli (ETEC) vaccine[1] |
