Apelin-13 is the 13-residue pyroglutamated form of the apelin peptide family that acts at the APJ receptor, with roles in cardiovascular regulation, fluid balance and metabolic signaling. Its short sequence and defined receptor pharmacology make it a standard tool in studies of APJ signaling, cardiac function and metabolic research, with the lyophilized format supporting accurate dosing. In cardiovascular and metabolic research, this 13-residue ligand is typically run in APJ-receptor activation assays, where inotropic and signaling readouts are measured across concentrations, and investigators compare the pyroglutamated form against longer apelin peptides. The lyophilized material reconstitutes for consistent dosing, and our records verify purity per batch. Trial and bulk quantities are available with secure packing. Every order of Apelin-13 carries the batch record and reconstitution notes, and the 13-residue ligand reconstitutes cleanly for APJ-receptor assays. We can supply matched vials for concentration-response studies and coordinate delivery within recommended conditions. Bulk supply is available, with the packing matched to the shipping route. As a factory-connected supplier, we keep stable stock of popular peptides and can accommodate custom pack sizes, OEM labeling and private-label requests. Shipments are handled by experienced logistics partners with secure packing and reliable delivery timelines.
