Apelin-36(human) is an endogenous orphan G protein-coupled receptor APJ agonist. Apelin-36(human) has a high affinity for the human APJ receptor expressed by HEK 293 cells. Apelin-36 (human) is related to two main biological activities: cardiovascular and metabolism. Studies have shown that Apelin-36 (human) can inhibit HIV-1 and HIV-2 from entering APJ-expressing NP2/CD4 cells. In peptide synthesis, Apelin-36 (human) is formed by the condensation of 36 amino acids and contains a large amount of arginine, which is a basic peptide.
