CD9 antibody

Catalog No. ABIN111919

Product Details anti-CD9 Antibody

Target: CD9

Reactivity: Human, Dog, Cat, Rabbit, Monkey

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD9 antibody is un-conjugated

Application: Flow Cytometry (FACS), Western Blotting (WB), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p)), Immunohistochemistry (Frozen Sections) (IHC (fro))

Specificity: Clone K41 detects CD9. Antigen distribution on Isolated cells: CD9 is mainly expressed on platelets, on early B-cells, and monocytes. Further reactivity could be seen with basophiles and eosinophiles. CD9 is used for the characterization of leukaemias and lymphomas. 90 % of non-T acute lymphoblastic leukaemic cells, 50 % of acute myeloid as well as chronic lymphoid leukaemias express the antigen. Tissue sections: glomeruli, sinus histiocytes, germinal centre, brain white matter, nerves, skin, and vascular smooth muscles.

Purification: Affinity chromatography.

Immunogen: Vero cells

Clone: K41

Isotype: IgG1

Application Details

Application Notes: Suitable for Immunohistochemistry on: Frozen sections: 2-5 μg/mL, 1/80-1/200). Paraffin sections: 8 μg/mL, 1/50, pretreatment is not necessary. Suggested positive control: human tonsil. Also works in FACS and Western blot.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.

Background: CD9 is a member of the tetraspan or transmembrane 4 superfamily. The family members (CD9, CD63, CD37, Cd53, CD81, CD82, CD151) show a high degree of homology in their membrane-spanning domain. CD9 is the only member with N-linked sugar bound to the first extracellular segment. Tetraspans are expressed by many cell types and show a different subcellular distribution. CD9 is constitutively surface-expressed by platelets and pre-B cells and is present in the alpha-granules of platelets. The participation of different tetraspan members in signalling complexes on B and T cells have been described. Furthermore, association of CD9 with beta1 integrins has been found. Anti CD9 monoclonal antibodies induce homotypic pre-B cell aggregation and fibronectin receptor-mediated adherence of these cells to bone marrow fibroblasts. Recent observations suggest a role of CD9 in adhesion.Synonyms: 5H9 antigen, Cell growth-inhibiting gene 2 protein, GIG2, Leukocyte antigen MIC3, MIC3, Motility-related protein, TSPAN29, Tetraspanin-29, p24
