背景介绍 S100A4 is a calcium-binding protein related to the S100 family of proteins. It is known also as a growth-related protein, CAPL. It is expressed at high levels in different mouse metastatic cells and in normal tissues (thymus, spleen) and activated macrophages, T-cells, neutrophils, monocytes, and macrophages. 产品介绍 Recombinant S100-A4 is a disulfide-linked homodimer protein consisting of 332 amino acid residues (containing a C-terminal IgG1 Fc tag), and migrates as an approximately 12 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human S100-A4 mature chain was expressed in E. coli.
询价背景介绍 Resistin was identified by screening for genes that are induced during the differentiation of adipocytes but down-regulated in mature adipocytes. Resistin gene expression is induced during the differentiation of adipocytes. Resistin circulates in mouse serum, and its level is increased markedly in obesity. Adipocytes secrete resistin as a unique signaling molecule that may be the hormone potentially linking obesity to type II diabetes, which is characterized by target-tissue resistance to insulin. TNF-alpha is a negative regulator of Resistin gene expression and inhibits Resistin mRNA expression and protein secretion by 70-90% in 3T3-L1 adipocytes. 产品介绍 Recombinant Resistin is a disulfide-linked homodimeric protein consisting of two 93 amino acid residues, and migrates as an approximately 20 kDa protein under non-reducing conditions and as a 10 kDa protein under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Resistin mature chain was expressed in E. coli.

询价背景介绍 RANTES belongs to the family of chemotactic cytokines known as Chemokines. RANTES is expressed by an early response gene. The synthesis of RANTES is induced by TNF-alpha and IL-1alpha. RANTES is chemotactic for T-cells, human eosinophils and basophils and plays an active role in recruiting leukocytes into inflammatory sites. RANTES also activates eosinophils to release eosinophilic cationic protein. It changes the density of eosinophils and makes them hypodense, which is thought to represent a state of generalized cell activation and is associated most often with diseases such as asthma and allergic rhinitis. RANTES also is a potent activator of oxidative metabolism specific for eosinophils. RANTES increases the adherence of monocytes to endothelial cells. It selectively supports the migration of monocytes and T-lymphocytes expressing the cell surface markers CD4 and UCHL1. These cells are thought to be pre-stimulated T-helper cells with memory T-cell functions. RANTES activates human basophils from some select basophil donors and causes the release of histamines. 产品介绍 Recombinant RANTES/CCL5 is a disulfide-linked monomer protein consisting of 69 amino acid residue subunits and migrates as an approximately 8 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human RANTES mature chain was expressed in E. coli.

询价背景介绍 Parathyroid hormone is a circulating hormone that acts as the central regulator of calcium metabolism by directly targeting bone, kidney, and intestine. The classical concept of PTH action is that it regulates serum calcium levels by stimulating bone resorption, however, intermittent administration of PTH selectively stimulates bone formation. It is now known that PTH binds to its receptor PTH1R, and activates the G protein α subunits.Besides PKA and PKC activation, PTH also regulates MAPKs including p42/p44 ERKs, p38, and c-Jun N-terminal kinase subtypes. 产品介绍 Recombinant Human PTH-84 is a disulfide-linked homodimeric protein consisting of 84 amino acid residues, and migrates as an approximately 9 kDa under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human PTH mature chain was expressed in E. coli.

询价背景介绍 Pigment epithelium-derived factor (PEDF), a 50- kDa secreted glycoprotein, is widely expressed throughout the human body, with expression decreasing during human hepatocellular carcinoma and breast cancer progression. PEDF binds to a cell membrane receptor to exhibit multifunctional activity in many cell types but its signaling mechanisms are largely unknown. PEDF exerts anti-angiogenic activity by arresting VEGF- or bFGF-mediated endothelial cell migration, inhibiting capillary morphogenesis, and inducing endothelial cell apoptosis. In human dermal microvascular cells, PEDF induces FasL expression and subsequently activation of caspase-8, which initiates the downstream apoptotic cascade. In human umbilical vein endothelial cells (HUVECs), its induction of apoptosis was shown to depend on p38 MAPK activity and to involve activation of caspases-8 and -9. 产品介绍 Recombinant human pigment epithelium-derived factor (PEDF) is a disulfide-linked monomer protein consisting of 440 amino acid residue subunits, and migrates as an approximately 45k Da protein under non-reducing and reducing conditions in SDS-PAGE. Source: Optimized DNA sequence encoding human PEDF mature chain was expressed in E. coli.
