背景介绍 Neuregulins (NDF, heregulin, GGF ARIA, or SMDF) are EGF-like growth and differentiation factors that signal through tyrosine kinase receptors of the ErbB family. The ErbB2 and ErbB4 receptors cooperate in transmission of neuregulin-1 signals in the heart, whereas ErbB2 and ErbB3 cooperate in neural crest cells. 产品介绍 Recombinant human Neuregulin-1 beta EGF domain is a disulfide-linked monomeric protein consisting of 62 amino acid residue subunits, and migrates as an approximately 7 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Neuregulin-1 beta EGF domain was expressed in E. coli.
询价背景介绍 NGF is mainly responsible for the survival and the differentiation and the functional activities of sensory and sympathetic neurons in the peripheral nervous system. It also plays an important role in the development and functional activities of cholinergic neurons in the central nervous system. Since NGF is synthesized also in non-neuronal tissues it may have a much wider spectrum of biological activities than thought previously. NGF stimulates chemotactic migration of human polymorphonuclear leukocytes in vitro. NGF stimulates the growth and differentiation of B-cells and the growth of T-cells and of some tumor cell types. NGF inhibits immunoglobulin production by various human plasma cell. The cytokines IL-1, IL-6, and bFGF are potent inducers of NGF. NGF induces the synthesis of IL-1 in pheochromocytoma cells which in turn acts as a growth factor for glial cells and induces the synthesis of NGF following nerve injuries. In thymic stromal cells NGF induces the synthesis of IL-6. NGF induces the synthesis of the fos oncogene and the myc oncogene and also influences the expression of EGF. One receptor that is responsible for mediating most of the activities of NGF is expressed preferentially in neuronal tissues. This glycoprotein of 140 kDa is the product of the trk gene. It possesses an intrinsic tyrosine-specific protein kinase in its intracellular domain. 产品介绍 Recombinant human NGF is as a non disulfide-linked homodimeric protein consisting of two 118 amino acid residues, and migrates as a 13 - 14 kDa protein under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Nerve Growth Factor mature chain was expressed in Chinese Hamster Ovary (CHO) cells.

询价背景介绍 The chemokine neutrophil- activating peptide 2 (NAP-2) is a 70-amino acid residue polypeptide that is formed from platelet-derived precursors by proteolytic processing. Mature NAP-2 stimulates various effector functions of polymorphonuclear neutrophil granulocytes (PMN) including directed chemotactic migration, exocytosis of lysosomal enzymes and secondary granule contents, and up-regulation of adhesion receptors. NAP-2 has been assigned to a subfamily now termed alpha-chemokines. The alpha-chemokines contain four cysteine residues at highly conserved positions, which enclose the core region of the molecules. The first two cysteines are separated by a single amino acid, forming a motif (CXC) that distinguishes the alpha-chemokine from the beta-chemokine subfamily, where these cysteines are in directly adjacent positions. 产品介绍 Recombinant NAP-2 is a disulfide-linked monomeric protein consisting of 71 amino acid residues and migrates as an approximately 8 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human NAP-2 (CXCL7) mature chain was expressed in E. coli.

询价背景介绍 CCL18, also designated dendritic cell (DC)3-derived CC chemokine 1, pulmonary and activation-regulated chemokine, alternative macrophage activation-associated CC chemokine 1, and MIP-4, is a human chemokine structurally related to CCL3. CCL18 was shown to be expressed in germinal centers of tonsils by dendritic cells and to attract mainly naive T cells, CD38–, mantle zone B lymphocytes and DC. The production of CCL18 by APC is enhanced by Th2 cytokines like IL-4 and IL-13 and suppressed by IFN-gamma. 产品介绍 Recombinant CCL18 is a disulfide-linked homodimeric protein consisting of 70 amino acid residues and migrates as an approximately 16 kDa protein under non-reducing conditions and 8 kDa under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human MIP-4 mature chain was expressed in E. coli.

询价背景介绍 Macrophage inflammatory protein (MIP)-3/CCL20, also known as liver and activation-regulated chemokine (LARC) or Exodus, is a member of the CC chemokine subfamily initially noted to be expressed in human liver, lung, appendix, and tonsillar crypts. MIP-3 is selectively chemotactic for CD34+ bone marrow cell-derived immature DCs and CD45RO+ memory T cells that express the cognate receptor CCR6. MIP-3 produced at sites of inflammation may chemoattract CCR6-expressing immature DCs to the subepithelial region of mucosal surfaces. 产品介绍 Recombinant MIP-3(CCL-23) is a disulfide-linked monomeric protein consisting of 100 amino acid residues and migrates as an approximately 11 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human MIP-3 mature chain was expressed in E. coli.
