3,3',5'-Triiodo-L-thyronine, also known as reverse T3 (rT3), is a thyroid hormone generated by deiodination of the prohormone thyroxine. It is about 1,000-fold less active at the thyroid hormone receptors TRalpha and TRbeta than 3,3',5-triiodo-L-thyronine (Cay-16028) and commonly described as inactive. However, high...

Angiotensin II is a peptide hormone known best as a vasoconstrictor with central roles in chronic hypertension, heart failure, and stroke. It is an octapeptide typically generated by the removal of two residues from angiotensin I by angiotensin-converting enzyme (ACE). Angiotensin II is a ligand for at least two...

Glucagon is a peptide hormone produced from proglucagon in pancreatic alpha cells that has a role in the regulation of glucose metabolism. Pulsatile application of glucagon to rat hepatocytes stimulates glucose production ex vivo. It also stimulates glucose output from perfused rat livers via increases in...

Sulfo-SMCC is a water-soluble protein cross-linking reagent that contains an anime-reactive sulfo-N-hydroxysuccinimide (sulfo-NHS) ester and a sulfhydryl-reactive maleimide group that can be used in the conjugation of proteins. It has been used to conjugate anti-programmed cell death ligand 1 (PD-L1) antibodies to...

[Ala1,3,11,15]-Endothelin-1 is an endothelin receptor type B (ETB) agonist and linear synthetic peptide derivative of endothelin-1 in which all four cysteine residues have been substituted with alanine. It selectively binds to ETB over ETA receptors (IC50s = 0.33 and 570 nM, respectively, for the porcine receptors)....

[Asp371]-Tyrosinase (369-377) is a naturally occurring tyrosinase antigen peptide. It is formed via post-translational modification of Asn371. [Asp371]-Tyrosinase (369-377) binds to MHC class I subtype HLA-A*0201-positive T2 cells (IC50 = 1.2 µg/ml) and induces lysis of HLA-A2.1-positive T2 cells incubated with...

Synthetic Strep-tag(R)II peptide recognized by Strep-Tactin(R), Strep-Tactin(R)XT as well as the monoclonal antibodies, StrepMAB-Classic and StrepMAB-Immo. It can be used for competitive elution of Strep-tag(R)II fusion proteins or as control protein in dot blot assays.

N-formyl-Nle-Leu-Phe-Nle-Tyr-Lys (fNLFNYK) is a synthetic chemotactic peptide. It binds to the formyl peptide receptor (FPR, Kd = 2.2 nM). fNLFNYK has been conjugated to various fluorophores to monitor FPR internalization.Formal Name: N-formyl-L-norleucyl-L-leucyl-L-phenylalanyl-L-norleucyl-L-tyrosyl-L-lysine,...

Atogepant is an antagonist of the calcitonin gene-related peptide (CGRP) receptor (IC50 = 0.026 nM). It is selective for the CGRP receptor over the adrenomedullin receptors (AM1) and AM2, calcitonin (CT) receptor, amylin receptor 1 (AMY1), and AMY3 receptor (IC50s = >18,000, 400, 6,274, 2.4 and 1,418 nM,...

KEMPFPKYPVEP Peptide is a peptide fragment of the dairy protein beta-casein. It can be produced by the protease M from A. oryzae and is found in dairy products fermented by fungi but not bacteria. KEMPFPKYPVEP Peptide (2 mg/kg) increases the levels of dopamine, norepinephrine, and homovanillic acid, but not...

Bradykinin (2-9) is a metabolite of the endogenous vasodilator peptide bradykinin (Cay-37408). It is formed from bradykinin via N-terminal cleavage by carboxypeptidase.Synonyms: BK (2-9), (Des-Arg1)-BK, (Des-Arg1)-Bradykinin, H-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg-OH. Molecular Formula: C44H61N11O10 . XCF3COOH. Formula...

Heparin-binding peptide is a synthetic peptide fragment corresponding to residues 1,892-1,899 of the C-terminal heparin-binding domain of fibronectin. It induces focal adhesion formation in pre-spread human embryonic fibroblasts (HEFs) when used at concentrations ranging from 1 to 1,000 µg/ml. Heparin-binding...
