Background: BLC (B-lymphocyte chemoattractant, murine equivalent of human B cell-attracting chemokine-1, BCA-1) is a 12 kDa, recently characterized ELR-CXC chemokine. BLC showed high levels of expression in spleen, Peyer's patches, and mesenteric lymph nodes. It is reported as the ligand of CXCR5. It attracts primarily B cells in vitro. Cell lines transfected with CXCR5 demonstrate both chemotaxis and calcium flux in response to BLC.

Catalog Number: TP-214
Size: Purified rabbit immunoglobulins, 0.5 mg
Product Description and Usage: For research use only. This polyclonal antibody, which reacts with recombinant and natural human eotaxin, was generated using E. coli-expressed amino acid 1-74 of mature human eotaxin as an immunogen. The tested titer for Western blot is 1:5,000. There is no cross-reactivity to mouse eotaxin; cross reactivity to eotaxin of other species has not been determined.

Background: Eotaxin is a 74-amino acid, eosinophil-chemotactic CC chemokine originally found in bronchoalveolar lavage fluid from allergic inflammatory subjects. The chemokine is involved in regulating the recruitment and activation of inflammatory leukocytes, particularly eosinophils. Eotaxin binds and activates the CCR3 chemokine receptor, and may play a fundamental role in the development of allergic responses.

Background: Fractalkine, also known as neurotactin, is a membrane-bound CX3C chemokine. The mature protein is part of a 397-amino acid precursor and consists of a chemokine domain of 76 amino acids, a mucin stalk of 241 amino acids, a putative transmembrane domain of 18 amino acids, and an intracellular tail of 37 amino acids. Within the chemokine domain the first two cysteine residues are separated by 3 amino acids (CX3C). Fractalkine message is found in high abundance in the brain, kidney, lung and heart tissues. Fractalkine is chemotactic for monocytes and other leukocytes including NK cells and may play a role in brain inflammation.

Background: IP-10 (interferon-gamma induced protein 10 kD; in mouse, also called cytokine responsive gene 2, Crg-2, or mob-1) is a highly inducible, primary response gene that belongs to the CXC chemokine superfamily. It was first cloned in 19851. The biological functions of IP-10 are still unclear. Like Mig, IP-10 has no activity on neutrophils. Its functions include stimulation of monocytes, natural killer and T-cell migration, regulation of T-cell and bone marrow progenitor maturation, modulation of adhesion molecule expression as well as inhibition of angiogenesis. Mig and IP-10 share the same receptor, CXCR32,3.

[PDF with figure || Place orders || Back to Ab list || Home Page]
Background: Rat MCP-1/JE (monocyte chemoattracctant protein-1) is a 148-amino acid CC chemokine with a NH2-terminal sequence of 29 residues as a signal sequence. It was originally cloned from Con A-stimulated rat spleen cDNA library. This rat MCP-1/JE is 49-amino acid longer than human MCP-1 at 3'-end. This 3'-end is a serine and threonine rich zone, which is probably responsible for the extensive O-glycosylation and explains for the higher molecular weight (25 kDa). In vitro, MCP-1/JE is chemotactic for monocytes as well as lymphocytes and basophils, but not for neutrophils. MCP-1/JE is produced by a wide range of cell types as a reaction to diverse inflammatory stimuli.

The tested titer for Western blot is 1:1,000. Cross-reactivity to RANTES of other species has not been determined.
[PDF with figure || Place orders || Back to Ab list || Home Page]
Background: RANTES (regulated upon activation, normal T-cell expressed and secreted) is a 70-amino acid CC chemokine originally cloned from T cell-specific sequences-enriched cDNA libraries. Both human and murine RANTES are chemotactic for monocytes. Human RANTES is also a chemoattractant for T cells and eosinophils, as well as an activator of basophils for histamine release. In contrast to other CC chemokines, RANTES is only slowly expressed after activation of leukocytes. It is involved in a number of pathological conditions like chronic inflammation and autoimmune diseases.

Background: SDF-1a (stromal cell-derived factor-a), also known as pre-B-cell growth-stimulating factor (PBSF), is a 70-amino acid CXC chemokine originally cloned from a bone marrow stromal cell line. Targeted deletion of SDF-1 gene resulted in defects of B-cell lymphopoiesis and bone marrow myelopoiesis. SDF-1 has been shown to be chemotactic for lymphocytes. In addition, SDF-1 was recently reported to be a ligand for CXCR4 (LESTR/fusin), a co-receptor for HIV-1 entry into T cells. SDF-1 binding to CXCR4 inhibits HIV-1 entry.

Background: Fractalkine, also termed neurotactin, is a membrane-bound CX3C chemokine. Rat CX3CR1, also named RBS11, was first cloned from rat brainstem, pituitary and/or spinal cord cDNA libraries. A G-protein-coupled seven-transmembrane domain receptor, it was recently identified to serve as fractalkine receptor. The human equivalent receptor is known as V28, which has been shown to mediate both the adhesive and migratory functions of fractalkine. Fractalkine and CX3CR1 represent new types of leukocyte trafficking regulators.

Background: CXCR4 (fusin) is a members in the seven-transmembrane domain G-protein-coupled chemokine receptor family. The full-length cDNA was isolated from a human spleen cDNA library1. Its ligand is chemokine stroma-derived factor (SDF). CXCR4 has been shown to be the co-receptor for HIV-1 binding to CD4 through the viral envelope glycoprotein gp1202. In other cases, CXCR4 can function as the only receptor for the interaction of HIV-2 with CD4 and host cells3. A mouse monoclonal antibody (12G5) to CXCR4 has been shown to inhibit HIV infectivity and HIV-induced syncytium.

Purified Rabbit Anti-human C3a receptor
Catalog Number: TP-504
Size: Purified rabbit immunoglobulins, 0.2 mg
Product Description and Usage: For research use only. This polyclonal antibody, which reacts with the human C3a receptor, was generated using E. coli-expressed human C3a receptor fragment (amino acids 161-332, corresponding to its second extracellular loop) as an immunogen. The antibody recognizes C3a receptor expressed in leukocytes and in transfected cells using flow cytometry.
[PDF with figure || Place orders || Back to Ab list || Home Page]
Background: C3a is an anaphylatoxin generated through activation of the complement C3. C3a is a potent chemoattractant for phagocytes, and it stimulates chemotaxis and other leukocyte functions. C3a binds to eosinophils, basophils, neutrophils, and differentiated U937 cells, that all express receptors for C3a on their cell surface. The C3a receptor has been cloned and shown to be a G protein-coupled receptor with seven putative transmembrane domains1,2. This receptor is characterized for its large extracellular loop between the fourth and fifth transmembrane domains3. The loop can be readily detected using the rabbit anti-C3a receptor antibody.

Background: Kaposi's carcoma-associated herpesvirus (KSHV, or human herpesvirus 8, HHV8), is a gamma herpesvirus that contain an open reading frame encoding a G protein-coupled receptor (GPCR) with putative 7 transmembrane domains. This GPCR has been shown to bind a number of chemokines including IL-8, NAP-2, PF-4, MGSA/Groa, I-309, RANTES, MCP-1, and MIP-1b1. The receptor is constitutively activated without chemokine binding, and it stimulates cell proliferation1. KSHV GPCR is also a viral oncogene that stimulates angio-genesis through induction of VEGF expression2. IP-10, a chemokine, can inhibit constitutively activated KSHV GPCR3.
