  • Human Interleukin-31

    规格:10 µg

    背景介绍 IL-31 is a recently discovered helical cytokine, belonging to the gp130/IL-6 cytokine family.The receptors for IL- 6 family are type I receptors, and they share a number of common structural motifs, such as the cytokine-binding domain with two pairs of conserved cysteine residues and a WSXWS sequence motif in the extracellular domain. IL-31 is expressed preferentially by activated Th2 CD4+ T cells, signaling through a heterodimeric receptor complex composed of IL-31RA and OSMR. Recent studies in both humans and mice have suggested a link between IL- 31/IL-31R expression and skin inflammation although the functional significance of endogenous IL-31/IL-31R interactions in influencing innate and adaptive immune responses remains unknown. 产品介绍 Recombinant Interleukin-31 is a disulfide-linked monomer protein consisting of 142 amino acid residues, and migrates as an approximately 18 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Interleukin-31 mature chain was expressed in E. coli.

  • Mouse Interleukin-3

    规格:10 µg

    背景介绍 IL-3 is produced mainly by T- cells following cell activation by antigens and mitogens, but also by keratinocytes, NK-cells, mast cells, endothelial cells, and monocytes. The analysis of bacterial- derived recombinant IL-3 shows that glycosylation is not required for the activity of IL-3. IL-3 sequences are evolutionarily not well conserved. Human and murine IL-3 show approximately 29% homology at the protein level while murine and rat IL-3 show approximately 54% homology. IL-3-alpha and IL-3- beta are two isoforms of rat IL-3. IL-3 receptors are expressed on macrophages, mast cells, eosinophils, megakaryocytes, basophils, bone marrow progenitor cells, and various myeloid leukemia cells. IL-3/IL-3 receptor complexes have a Kds of 10-9 - 10-10 M. Binding of IL-3 to its receptor causes specific phosphorylation of a 150 kDa membrane glycoprotein. 产品介绍 Recombinant mouse IL-3 is a disulfide-linked monomer consisting of 135 amino acid residues, and migrates as an approximately 15 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding murine Interleukin-3 mature chain was expressed in E. coli.

  • Human Interleukin-29

    规格:20 µg

    背景介绍 The IFN-lambda gene family is composed of three distinct genes: IFN-lambda1 (IL-29), IFN-lambda2 (IL- 28A), and IFN-lambda3 (IL- 28B) . IFN-lambda proteins exhibit only weak homology to IL-10, but, like IL-10, they also use the IL-10R2 chain as a component of their receptor complex. The IFN-receptor complex consists of the unique ligand-binding chain IFN- R. The IFN-λ1 gene is found exclusively in primate genomes and is 81% identical to IFN-λ2/3. IFN-λs, which are now collectively referred to as type III IFNs, exhibit several features in common with type I IFNs, such as antiviral, antiproliferative, and antitumor activities. 产品介绍 Recombinant Interleukin-29 (IFN-lambda) is a disulfide-linked monomer protein consisting of 178 amino acid residues, and migrates as an approximately 20 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding murine Interleukin-29 mature chain was expressed in E. coli.

  • Human Interleukin-21

    规格:10 µg

    背景介绍 IL-21 stimulates proliferation of B-cell stimulated by crosslinking of the CD40 antigen. It inhibits proliferation stimulated by IL-4 plus anti-IgM. IL-21 augments stimulation of the proliferation of naive CD45RA(+) but not memory CD45R0(+) T-cells mediated by engagement of CD3. IL-21 stimulates the proliferation of bone marrow progenitor cells and the expression of the NK-cell marker CD56 in the presence of IL-15. The Interleukin-21 receptor is closely related to human IL-2 beta receptor. The receptor contains a WSXWS motif in the extracellular region, typical of type 1 cytokine receptors. The receptor is expressed on NK-cells, T- cells, and B-cell line. The functional signaling complex activates Janus kinases JAK1, JAK3, and the STAT proteins STAT1, and STAT3. 产品介绍 Recombinant IL-21 is a disulfide-linked homodimeric protein consisting of 132 amino acid residues, and migrates as an approximately 15 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding murine Interleukin-21 mature chain was expressed in E. coli.
