It has been used extensively as a general epitope tag in expression vectors. DYKDDDDK-tag Antibody, pAb, Rabbit can be used to detect...

Cathepsin B is an enzymatic protein that is a member of the peptidase (or protease) family. Elevated levels of cathepsin B occur in a wide variety of disease, causing numerous pathologies including cell death, inflammation, and the production of toxic peptides. For example, neuroscience research...

B7-1/CD80 and B7-2/CD86, together with their receptors CD28 and CTLA-4, constitute one of the dominant co-stimulatory pathways that regulate T- and B-cell responses. Although both CTLA-4 and CD28 can bind to the same ligands, CTLA-4 binds to B7-1 and B7-2 with a 20-100 fold higher affinity than CD28...

The alpha factor pheromone arrests yeast in the G1 phase of their cell cycle. Alpha Factor Mating Pheromone induces the expression of mating genes, changes in nuclear architecture, and polarzes growth toward the mating partner. STE2 encodes the alpha factor pheromone receptor (a GPCR) found on...

MIP-3a/CCL20, also known as LARC (Liver and Activation-regulated Chemokine) and as Exodus, is a CC chemokine that is expressed in the liver, lymph nodes, appendix, PBL and lung and can signal through the CCR6 receptor. MIP-3 alpha is chemotactic towards lymphocytes and dendritic cells. Additionally,...

MRGX2 is a Gq- and Gi-coupled GPCR that binds to several peptides, including the neuropeptide cortistatin-14 and the proadrenomedullin N-terminal peptide (PAMP). It is probably involved in the function of nociceptive neurons and regulation of nociceptor function and/or development, including the...

GenScript Protein G Resin FF is an affinity chromatography medium designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media. The recombinant protein G ligand is coupled to 4% highly cross-linked agarose. The...

Interleukin-6 (IL-6, also known as IFN-ß2) is a pleiotropic cytokine that plays important roles in acute phase reactions, inflammation, hematopoiesis, bone metabolism, and cancer progression. IL-6 is secreted by T cells and macrophages to stimulate immune response. IL-6 is responsible for...

Protein C is a Vitamin K-dependent plasma zymogen that is activated by proteolytic cleavage of the thrombin-thrombomodulin complex to form an anticoagulant enzyme. Protein C Tag is a 12 amino acid sequence EDQVDPRLIDGK, which encodes residues 6 through 17 of the heavy chain of the protein.Protein C...

ADORA1 is a receptor for adenosine. It is demonstrated that the ADORA1 receptor is ubiquitous throughout the entire body. Activation of ADORA1 elicits an inhibition of adenylate cyclase and therefore a decrease in the cAMP concentration. ADORA1 receptors are implicated in sleep promotion by...

The glucagon-like peptides include glucagon, GLP-1, and GLP-2 exert diverse actions on nutrient intake, gastrointestinal motility, islet hormone secretion, cell proliferation and apoptosis, as well as nutrient absorptionand assimilation. Glucagon-like peptide (GLP)-2, a product of the proglucagon...

Interleukin-18 (IL18, also known as interferon-gamma inducing factor or IGIF) is a cytokine that belongs to the IL-1 superfamily and is produced by macrophages and other cells. Its biological activity is pleiotropic and it has been shown to induce interferon-gamma production in KG-1 cells. The...

Glucagon is a single-chain polypeptide that contains 29 amino acid residues and has a molecular weight of 3,483. Glucagon is a hormone produced in the pancreas and it is used to raise very low blood sugar. Glucagon is also used in diagnostic testing of the stomach and other digestive organs....

Aß (1-42), a major component of amyloid plaques, accumulates in neurons of Alzheimer’s disease brains. Biochemical analysis of the amyloid peptides isolated from Alzheimer’s disease brain indicates that Aß (1-42) is the principal species associated with senile plaque amyloids, while Aß (1-40) is...

Transforming growth factor beta 3(TGFB3) is a member of a TGF -ß superfamily which is defined by their structural and functional similarities. TGFB3 is secreted as a complex with LAP. This latent form of TGFB3 becomes active upon cleavage by plasmin, matrix metalloproteases, thrombospondin -1, and a...

The P2Y receptor 12 (P2Y12) is a G_i-coupled GPCR expressed in platelets, brain tissues, vascular smooth muscle cells. P2Y12 can sustain platelet aggregation and promote thrombus growth and stabilization. It also plays a function in dense and alpha granule secretion, p-selectin expression...

Nonapeptide-1 prevents melanin synthesis by preventing activation of the tyrosinase.

Platelet factor 4 , also known as CXCL4, is expressed in megakaryocytes and stored in the a-granules of platelets. Recombinant human PF-4 is a 7.8 kDa protein containing 70 amino acid residues, including the four highly conserved residues present in CXC chemokines. Platelet factor 4 can be...

Interleukin-3 (IL-3) is a pleiotropic cytokine belonging to the interleukin family. IL-3 shares similarities with Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) and IL-5: they all have a four-helix bundle structure, are located on the same chromosomes in both human and mouse, are produced...

Oncostatin M (OSM) is a multifunctional cytokine, and belongs to Interleukin-6 (IL-6) subfamily, which also includes IL-11, leukemia inhibitory factor (LIF), ciliary neurotropic factor, cardiotrophin-1, and novel neurotropin-1. In vivo , OSM is secreted from activated T cells, monocytes,...

Interleukin-1 receptor antagonist (IL-1ra) is a member of the IL-1 family. Endogenous IL-1ra is produced in numerous animal disease models as well as in human autoimmune and chronic inflammatory diseases. It binds to IL-1 receptors in competition with IL-1, but does not elicit intracellular response...
