Produktdetails anti-CD4 Antikörper

Spezifität: The antibody MEM-115 recognizes an epitope in the D1 domain of CD4 antigen, a 55 kDa transmebrane glycoprotein expressed on a subset of T lymphocytes (helper T cells) and also on monocytes, tissue macrophages and granulocytes.

Kreuzreaktivität (Details): Species reactivity (tested):Human.

Aufreinigung: Affinity Chromatography on Protein A

Immunogen: Human thymocytes and T lymphocytes

Isotyp: IgG2a

Anwendungsinformationen

Applikationshinweise: Excellent for Immunoprecipitation. Functional The antibody MEM-115 blocks binding of HIV gp120 to CD4 Molecule and it also strongly inhibits CD4-MHC Class II interactions. Flow Cytometry: Although it has not been tested rigorously, following data suggest that the antibody MEM-115 is a low-affinity antibody: its binding to T cells increases at elevated temperature, monovalent Fab fragments essentially do not bind to T cells. MEM-115 is negative in Western blotting even with non-reduced samples of cell lysates.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.

Details zu CD4

Target: CD4

Andere Bezeichnung: CD4

Hintergrund: CD4 is a single chain transmembrane glycoprotein and belongs to immunoglobulin supergene family. In extracellular region there are 4 immunoglobulin-like domains (1 Ig-like V-type and 3 Ig-like C2-type). Transmembrane region forms 25 aa, cytoplasmic tail consists of 38 aa. Domains 1,2 and 4 are stabilized by disulfide bonds. The intracellular domain of CD4 is associated with p56Lck, a Src-like protein tyrosine kinase. It was described that CD4 segregates into specific detergent-resistant T-cell membrane microdomains. Extracellular ligands: MHC class II molecules (binds to CDR2-like region in CD4 domain 1), HIV envelope protein gp120 (binds to CDR2-like region in CD4 domain 1), IL-16 (binds to CD4 domain 3), Human seminal plasma glycoprotein gp17 (binds to CD4 domain 1), L-selectin Intracellular ligands: p56Lck CD4 is a co-receptor involved in immune response (co-receptor activity in binding to MHC class II molecules) and HIV infection (human immunodeficiency virus, CD4 is primary receptor for HIV-1 surface glycoprotein gp120). CD4 regulates T-cell activation, T/B-cell adhesion, T-cell diferentiation, T-cell selection and signal transduction. Defects in antigen presentation (MHC class II) cause dysfunction of CD4+ T-cells and their almost complete absence in patients blood, tissue and organs (SCID immunodeficiency).Synonyms: T-cell surface antigen T4/Leu-3, T-cell surface glycoprotein CD4
