H-Gly-Arg-pNA dihydrochloride (H-Gly-Arg-Pna 2HCl) belongs to the class of peptides that bind to 1,2 thrombin and can be quantified by colorimetric detection at 405 nm as a measure of thrombin activity.

Bz-Nle-Lys-Arg-Arg-AMC is a fluorescent tetrapeptide substrate for the quantitative detection of dengue virus (DV) NS2B-NS3 protease, yellow fever virus (YFV) NS3 protease and Zika virus NS3 protease activities. The rate of release of the cleavage product of the protease, AMC (7-amino-4-methylcoumarin), was observed by hydrolysis reaction to calculate the enzyme activity, with excitation/emission maxima at 340-360/440-460 nm, respectively.

Arg-Gly-Asp-Cys TFA serves as the binding motif through which fibronectin interacts with cell adhesion molecules. This compound has the ability to hinder platelet aggregation and fibrinogen binding.

H-D-Phe-Pip-Arg-pNA dihydrochloride (S-2238 dihydrochloride), a chromogenic substrate, mimics the N-terminal fragment of the A alpha chain of fibrinogen, the native substrate of thrombin. Specifically designed for thrombin detection, it is employed for quantifying antithrombin-heparin cofactor (AT-III) and is characterized by its sensitivity, accuracy, and ease of implementation.

Arg-Gly-Asp TFA (99896-85-2(free base)) (RGD Trifluoroacetate) is a tripeptide that effectively triggers cell adhesion, addresses certain cell lines and elicits specific cell responses; binds to integrins.

Arg-Gly-Asp-Ser (TFA) is an integrin-binding sequence that inhibits integrin receptor function by specifically and directly binding to pro-caspase-8, pro-caspase-9, and pro-caspase-3, without interacting with pro-caspase-1 [1].

[Des-Arg9]-Bradykinin ([Des-Arg9]-Bradykinin(2TFA))(2TFA) is an agonist of Bradykinin (B1) receptor.

Nona-L-arginine (Arg)9 acetate, a cell-penetrating peptide (CPP) consisting of 9 arginine residues, displays neuroprotective properties, with an IC50 of 0.78 μM in the glutamic acid model [1] [2].

[Leu144,Arg147]-PLP (139-151) is a mutated fragment of the myelin proteolipid protein (PLP), featuring substitutions of tryptophan to leucine and histidine to arginine at positions 144 and 147, respectively. Immunizing mice with this peptide (50 µg) mixed in complete Freund's adjuvant (CFA) elevates IL-4 levels in the spleen. While it suppresses Th1 cell activation in vitro, it does not do so in vivo; instead, it promotes the development of regulatory T cells. Preimmunization with [Leu144, Arg147]-PLP (139-151) postpones the onset of experimental autoimmune encephalomyelitis (EAE) triggered by encephalitogenic peptides from PLP (178-191), myelin oligodendrocyte glycoprotein (MOG) (92-106), or myelin basic protein (MBP) in mice.

Z-Gly-Gly-Arg-AMC TFA (66216-78-2 free base) is a thrombin-specific fluorogenic substrate used to assess thrombin generation in platelet-rich plasma (PRP) and platelet-poor plasma (PPP).

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).

N-CBZ-Phe-Arg-AMC hydrochloride (Z-Phe-Arg-Amc HCl) is a substrate for catS protease. CatS protease is an important member of the cysteine protease family and is a lysosomal protease.
