Elabela(19-32)（Cat No.:I015137）is a bioactive peptide fragment of the endogenous hormone Elabela, also known as Toddler, which functions as a ligand for the apelin receptor (APJ). This truncated peptide retains strong receptor binding and signaling capacity, regulating cardiovascular development, vascular tone, fluid balance, and energy metabolism. It has gained interest as a research tool for exploring cardiovascular disease mechanisms, angiogenesis, and metabolic disorders. Elabela(19-32) is particularly valuable in probing peptide-GPCR interactions and evaluating novel therapeutic approaches targeting the apelinergic system.
