Phe-Met-Arg-Phe-likepeptide, derived from the visceral and somatic muscles of the snailHelixaspersa, is a neuropeptide known as FMRF (Phe-Met-Arg-Phe). This peptide comprises four amino acid residues[1].
H-D-Phe-Pip-Arg-pNA hydrochloride, a chromogenic substrate, mimics the N-terminal segment of the A alpha chain of fibrinogen, the native substrate of thrombin. It displays specificity towards thrombin and is employed for quantifying antithrombin-heparin cofactor (AT-III). The utilization of H-D-Phe-Pip-Arg-pNA hydrochloride in the AT-III assay enables a sensitive, accurate, and straightforward measurement process.
Glucagon-likepeptide 1 (1-37), human (TFA), is a highly potent agonist of the GLP-1 receptor and is a pancreatic hormone synthesized through post-translational processing of proglucagon.
Glucagon-likepeptide 1 (1-37), human, is a highly potent agonist of the GLP-1 receptor and a pancreatic hormone synthesized through post-translational processing of proglucagon. Unlike truncated forms of GLP-1, it has no effect on food intake in rats.
N-CBZ-Phe-Arg-AMC (Z-FR-AMC) is a substrate for serine proteases, including cathepsins, kallikrein, and plasmin. The substrate exhibits absorption emission at 330 390 nm (weak fluorescence), while the end product (AMC) shows absorption emission at 342 441 nm (strong fluorescence).
{Boc}-Phe-Leu-Phe-Leu-Phe ({Boc}-FLFLF) is a selective antagonist of the formyl peptide receptor (FPR) family, effectively inhibiting receptor activity in response to formyl peptides.
H-D-Phe-Pip-Arg-pNA (S-2238) acetate is a chromogenic substrate designed based on the N-terminal fragment of the A alpha chain of fibrinogen, which is the physiological target of thrombin. As a specific indicator of thrombin activity, H-D-Phe-Pip-Arg-pNA acetate is utilized to quantify. This assay, utilizing H-D-Phe-Pip-Arg-pNA acetate, ensures high sensitivity, accuracy, and ease of execution.
