Bovine CD40 Ligand ELISA

Kingfisher Biotech's Bovine CD40 Ligand Do-It-Yourself ELISA (Catalog # DIY1211B-003) contains capture antibody, protein standard, and detection antibody for development of a CD40 Ligand ELISA. The antibodies have been determined to function in an ELISA with the standard provided.

CD40 Ligand (CD40LG) is a transmembrane protein that is a member of the TNF superfamily. In addition to existing in a membrane bound form, CD40LG can also be released as a soluble molecule (sCD40LG), which has been shown to have biological functions.

CD40 interacts with CD40 ligand (aka CD40LG, TNFSF5 or CD154), which is predominantly expressed on activated CD4+ T-cells. CD40LG is transiently expressed on activated T-cells and plays a crucial role in B-cell function. Activated T-cells expressing CD40LG can also interact with CD40 on endothelial cells to induce production of inflammatory cytokines. The transient expression of CD40LG allows T-cells to stimulate selected CD40-bearing cells to participate in the immune response.

Swine SCF Recombinant Protein

SCF, often known as Kit Ligand, KITL or KITLG, is involved in pathways that control the regulation of cell survival, migration and proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, and melanogenesis. SCF binding to the receptor-type protein-tyrosine kinase KIT, induces a cell signaling pathway that activates several other cell signaling pathways, including PIK3R1/AKT1, GRB2, RAS, RAF1, MAPK1/ERK2, MAPK3/ERK1, and STAT signaling events. The effects of SCF on these secondary pathways further allow it to play a role in many or the major cellular processes. The SCF, of most vertebrates, has a soluble form as well as the membrane bound type I receptor form. Mutations in the SCF pathway may result in a broad range of abnormalities including anemia, and sterility. SCF and KIT interaction has been shown to promote the growth of cancer cells and organoids in culture, and xenograft tumors in mice. SCF is being utilized in many animal model systems, from metastasis research in breast tumor-bearing arthritic mice to the genetic linkage to de-pigmentation in pigs. Interestingly, a second SCF pathway was retained in zebrafish, after a whole genome duplication, and is now undergoing divergent evolution.

Kingfisher Biotech's Swine SCF recombinant protein was produced in yeast and therefore does not have endotoxin, is naturally folded, and post-translationally modified. It has a predicted molecular weight of 18.7 kDa.

Swine IL-28B Recombinant Protein

IL-28B, IL-28A, and IL-29 are three closely related IFN-lambda cytokines that can be induced by viral infection that induce signaling through the Jak/STAT pathway. IL-28B, and other IFN-lambda cytokines, are well established as having several antiviral and anti-cancer activities. IFN-lambda, restricts virus from spreading into the brain and plays a major role in chronic viral infections found in the gastrointestinal tract. IL-28B, like other IFN-lambda cytokines, modulates innate and adaptive immunity, autoimmunity, and tumor progression. Unlike type I IFNs, which are able to stimulate most cell types, IL-28B, along with the other IFN-lambda cytokines, stimulation appears to be limited to dendritic cells and some tumor cell lines. Due to the affect IL-28B has on the adaptive immune system, it has gained much interest as an immunotherapeutic agent for treatment of allergic asthma. The IL-28 cytokines control T cell responses in vivo through the modulation of lung CD11c(+) DC function in experimental allergic asthma animal models. IFN-lambda cytokines, including IL-28B, have been shown to interact with a heterodimeric, class II cytokine receptor that consists of the IL-10 receptor, beta (IL-10RB) and the IL-28 receptor, alpha (IL-28RA) subunits. The promiscuous IL-10RB subunit is also common to IFN-alpha/beta family members, but the IL-28RA subunit is specific for the IFN-lambda cytokines, IL-28B, IL-28A, and IL-29.

Kingfisher Biotech offers Swine IL-28B in three sizes - 5 UG, 25 UG, and 100 UG.

Oncostatin M Proteins

OSM (Oncostatin M) is a secreted cytokine involved in homeostasis and most chronic illnesses. OSM, a member of the IL-6 (gp130) family of proteins, inhibits the proliferation of a number of tumor cell lines and plays a significant role in hematopoiesis, mesenchymal stem cell differentiation, liver regeneration, heart remodeling, nociception, inflammation and metabolism. Of all IL-6-type cytokines studied so far, OSM displays the broadest signaling profile. LIF and OSM proteins activate the JAK/STAT pathway, the MAPK protein kinases ERK1 and ERK2, the stress-activated protein kinases p38 and c-Jun N-terminal kinase (JNK), the phosphatidylinositol-3-kinase (PI3K) AKT pathway and protein kinase C delta (PRKCD). In addition, OSM exhibits many other effects by regulating the production of other cytokines including IL-6, G-CSF and GM-CSF in endothelial cells. OSM may be a tumor promoter that will provide a potential target for antiangiogenic therapy.

Kingfisher Biotech's current portfolio of Oncostatin products, includes bovine and canine recombinant proteins with more in the development queue.

VS1196B-002
C-X-C motif chemokine 10 (CXCL10) also known as Interferon gamma-induced protein 10 (IP-10) or small-inducible cytokine B10 is a member of the C-X-C chemokine family. CXCL10 (IP-10) is secreted by several cell types in response to IFN-gamma. These cell types include monocytes, endothelial cells and fibroblasts. CXCL10 (IP-10) has been attributed to several roles, such as chemoattraction for monocytes/macrophages, T cells, NK cells, and dendritic cells, promotion of T cell adhesion to endothelial cells, antitumor activity, and inhibition of bone marrow colony formation and angiogenesis.

Canine IL-8 ELISA

Interleukin-8 (IL-8), also known as CXCL8, is a CXC family member chemokine produced by macrophages and other cell types such as epithelial cells. There have been 17 different CXC chemokines described in mammals, that are subdivided into two categories, those with a specific amino acid sequence (or motif) of glutamic acid-leucine-arginine (or ELR for short) immediately before the first cysteine of the CXC motif (ELR-positive), and those without an ELR motif (ELR-negative). ELR-positive CXC chemokines such as IL-8 specifically induce the migration of neutrophils, and interact with chemokine receptors CXCR1 and CXCR2.

The Canine IL-8 Do-It-Yourself ELISA from Kingfisher Biotech contains capture antibody, standard, and detection antibody for development of a Canine IL-8 ELISA. The antibodies have been determined to function in an ELISA with the standard provided.

Cynomolgus Monkey IL-6 ELISA

Interleukin-6 (IL-6) is an interleukin that acts as both a pro-inflammatory and anti-inflammatory cytokine. It is secreted by T cells and macrophages to stimulate immune response to trauma, especially burns or other tissue damage leading to inflammation. IL-6 is also produced from muscle, and is elevated in response to muscle contraction. It is significantly elevated with exercise, and precedes the appearance of other cytokines in the circulation. Osteoblasts secrete IL-6 to stimulate osteoclast formation. Smooth muscle cells in the tunica media of many blood vessels also produce IL-6 as a pro-inflammatory cytokine. The role of IL-6 as an anti-inflammatory cytokine is mediated through its inhibitory effects on TNF-alpha and IL-1, and activation of IL-1ra and IL-10.

The Cynomolgus Monkey IL-6 Do-It-Yourself ELISA from Kingfisher Biotech contains capture antibody, standard, and detection antibody for development of a Cynomolgus Monkey IL-6 ELISA. The antibodies have been determined to function in an ELISA with the standard provided.
