Gastric Inhibitory Polypeptide (1-30), porcine, deficient in the 12 C-terminal amino acids of the natural gastric inhibitory polypeptide (GIP), demonstrates biological activity by enhancing the release of insulin and somatostatin [1].

Pancreatic polypeptide, a peptide produced by the pancreas's endocrine PP cells, modulates pancreatic secretory functions and influences hepatic glycogen levels and gastrointestinal secretion [1].

Human membrane-bound PD-L1 polypeptide serves as an antigen for inducing the production of PD-L1 antibodies [1].

Gastric Inhibitory Polypeptide (6-30) amide (human) is an incretin hormone used in diabetes research [1].

Antifreeze Polypeptide 6 (winter flounder) is one of the winter flounder's antifreeze polypeptides, which depresses the freezing point of plasma by inhibiting the expansion of ice nuclei [1].

Pancreatic Polypeptide, rat, is an agonist of the NPY receptor with high affinity at NPYR4. Pancreatic Polypeptide (PP) is a 36-amino acid, C-terminally amidated peptide and a member of the PP-fold peptide family. It is produced and secreted by the PP cells of the islets of Langerhans.

Pancreatic Polypeptide, rat acetate is a natural product and an NPY receptor agonist with high affinity for NPYR4 and receptor selectivity, commonly used in experimental models studying energy balance, feeding behavior, and related metabolic diseases.

Endogenous high affinity agonist for human NPY Y4 receptor (Ki = 0.056 nM). Believed to play an important role in the function of the gastrointestinal tract.

Agonist at Y4 neuropeptide Y receptors.

Potent, selective peptide agonist for the neuropeptide Y Y5 receptor (IC50 values for inhibition of NPY binding to human Y5, Y1, Y2 and Y4 receptors are 0.24, 530, > 500, and 51 nM respectively, Ki at Y5 = 0.1 - 0.15 nM). Stimulates food intake in vivo.

Pancreatic polypeptide TFA acts as a neuropeptide Y (NPY) Y4/Y5 receptor agonist.

TAT-NSF222scr Fusion Polypeptide, scrambled, serves as a control peptide for the TAT-NSF700 Fusion Peptide. It consists of the full TAT domain followed by the scrambled sequence of NSF 222-243 amino acid residues.

GIP (3-42), human (Gastric Inhibitory Polypeptide (3-42) (human)) is a peptide that acts as a glucose-dependent proinsulinotropic polypeptide (GIP) receptor antagonist and regulates insulin secretion and the metabolic effects of GIP in vivo, which can be used to study type 2 diabetes.

Gastric Inhibitory Peptide (1-42) (porcine) TFA is a glucose-dependent insulinotropic polypeptide released by intestinal K-cells. It stimulates insulin secretion while inhibiting gastric acid secretion and gastrointestinal motility, thereby regulating digestive function.

Gastric inhibitory peptide 1 (GIP-1) (3-42), a fragment of the incretin hormone GIP and antagonist to the GIP receptor, is generated through the action of serum dipeptidyl peptidase 4 (DDP-4). When administered at 25 nmol/kg to an ob/ob mouse diabetes model, GIP-1 (3-42) elevates plasma glucose levels and lowers plasma insulin levels, demonstrating its effect on reducing insulin secretion from BRIN-BD11 pancreatic cells at a concentration of 100 nM.

Brain natriuretic peptide-32 (BNP-32), a fragment of the proBNP cardiovascular hormone precursor, exhibits affinity for natriuretic peptide receptors in rat vascular smooth muscle cells (IC50 = 7.3 nM) and promotes cGMP accumulation within these cells (EC50 = 170 nM). Additionally, BNP-32 effectively mediates the relaxation of norepinephrine-precontracted isolated rat aortic strips (EC50 = 6.7 nM). Upon administration at a dosage of 3 µg/kg, it elevates urine and urinary electrolyte outputs and induces hypotension in rats.

PACAP (1-38), human, ovine, rat TFA is an endogenous neuropeptide and a high-affinity agonist for the PAC1 receptor. This 38-amino acid peptide binds to the PAC1 receptor to activate adenylate cyclase, inducing an increase in intracellular cAMP levels and triggering downstream signaling. Research demonstrates that C-terminal amidation of PACAP (1-38), human, ovine, rat TFA is dispensable for its biological activity at the PAC1 receptor, with the non-amidated form retaining full agonistic potency. It plays crucial roles in neuroprotection, regulation of insulin secretion, and vasodilation.

Atrial Natriuretic Peptide (ANP) (1-28), human, porcine Acetate is an atrial natriuretic peptide (ANP) hormone secreted by atrial myocytes that is capable of acting as an natriuretic peptide receptor-A(NPR-A) agonist, used in the treatment of acute decompensated heart failure (ADHF). By binding to specific receptors on the surface of the kidney, blood vessel, and heart cells, Carperitide causes an increase in cyclic guanosine monophosphate (cGMP) levels and induces vasodilatation, diuresis, and sodium excretion, which in turn reduces the heart's workload.

PACAP (1-38), human, ovine, rat (Pituitary Adenylate Cyclase Activating Polypeptide 38), is a neuropeptide comprising 38 amino acid residues.
