Apelin-13 TFA（Cat No.:I046136）is a potent bioactive fragment of the apelin peptide family, acting as a high-affinity ligand for the APJ (APLNR) receptor. It regulates cardiovascular function, fluid homeostasis, angiogenesis, and energy metabolism. Apelin-13 modulates blood pressure, cardiac contractility, and insulin sensitivity, making it highly relevant in studies of cardiovascular disease, diabetes, and metabolic syndrome. The TFA salt form improves solubility and stability for laboratory applications. Apelin-13 TFA serves as a critical research tool for exploring GPCR-mediated signaling pathways and therapeutic targets in metabolic and vascular disorders.
