Proteins and Peptides

Fibrinogen is a plasma clotting factor composed of three different polypeptide chains (alpha, beta and gamma). Under chronic inflammatory conditions, fibrinogen can be acted upon by the enzyme peptidylarginine deiminase 4 (PAD4), converting specific arginine residues to citrulline. Patients with rheumatoid arthritis...

Growth Hormone purity was determined to be greater than 98% as determined by analysis by UV-Spectroscopy at 280nm and by reducing and non-reducing SDS-pAGE. Protein function: Plays an important role in growth control. Its major role in stimulating body growth is to stimulate the liver and other tissues to secrete...

Human transferrin is encoded by the TF gene and is an iron-binding blood plasma glycoprotein that controls the level of free iron in biological fluids. Human transferrin binds iron very tightly but reversibly. Human transferrin is the most important iron pool in mammals. Human transferrin has a molecular weight of...

Solid lyophilized powder. Soluble in water. Mitochondria-derived peptide (MDP), Promotes biosynthesis of the endogenous AMP analog AICAR and consequently AMP-activated protein kinase (AMPK), Induces cellular and systemic glucose uptake and improves insulin sensitivity. Shown to prevent diet-induced obesity (DIO) in...

Z-AEVD-FMK is an irreversible inhibitor of caspase-10 and related caspases. At 10 µM, it can prevent the initiation of Fas signaling by caspase-10 in Jurkat T lymphoma cells, preventing Bid cleavage into its active form, caspase cascade activation, and apoptosis.

Ac-LETD-AFC is a fluorogenic substrate that can be cleaved specifically by caspase-8. Caspase activity can be quantified by fluorescent detection of free AFC (also known as 7-amino-4-trifluoromethylcoumarin), which is excited at 400 nm and emits at 505 nm.

GDP-L-Fucose synthase, encoded by the gene TSTA3, is an NADP(H)-binding protein that catalyzes the final step in the synthesis of GDP-L-fucose from GDP-D-mannose. It converts GDP-4-keto-6-deoxy-D-mannose to GDP-L-fucose via a two-step reaction consisting of epimerization followed by NADPH-dependent reduction....

PAR2 (1-6) is a synthetic peptide agonist of proteinase-activated receptor 2 (PAR2) that corresponds to residues 1-6 of the amino terminal tethered ligand sequence of mouse and rat PAR2. It also corresponds to residues 39-44 and 37-42 of the mouse and rat full-length sequences, respectively. PAR2 (1-6) induces...

PAR4 (1-6) is a peptide agonist of proteinase-activated receptor 4 (PAR4) that corresponds to residues 1-6 of the amino terminal tethered ligand sequence of human PAR4 and residues 48-53 of the full-length sequence. It activates PAR4 and the cleavage site mutant PAR4R47A when used at a concentration of 500 µM. PAR4...

PAR3 (1-6) is a synthetic peptide agonist of proteinase-activated receptor 1 (PAR1) that corresponds to residues 1-6 of the amino terminal tethered ligand sequence of human PAR3 and residues 39-44 of the full-length human sequence. PAR3 (1-6) activates p42/44 MAPK signaling in fibroblasts expressing PAR1, but not...

Acetyl tetrapeptide-3 is a biomimetic peptide. It increases protein levels of type III collagen and total laminins in MRC5 human fibroblasts when used at a concentration of 1 µM. Acetyl tetrapeptide-3 reverses corticoid-induced decreases in collagen VII expression at the dermal-epidermal junction in human skin...
