CD314 (NKG2D) Monoclonal Antibody (CX5), Functional Grade, eBioscience™, Invitrogen™

Description

Description: The CX5 monoclonal antibody reacts with the mouse NKG2D, a lectin-like molecule expressed on both human and mouse NK cells. Mouse NKG2D binds to retinoic acid-inducible RAE-1alpha, -beta, -gamma, -delta, -ε and the minor histocompatibility molecule H60 and has the ability to costimulate multiple NK activation receptors, through the DAP12/DAP10 adaptor molecules. NKG2D is expressed by all spleen and liver NK cells, NK1.1^+ thymocytes, in vitro activated LAK cells, and a subset of splenic NKT cells. Applications Reported: The CX5 antibody has been reported for use in flow cytometric analysis. It has also been reported in blocking of binding of NKG2D to its ligands, RAE-1 and H60, and inhibition NKG2D-dependent NK cell-mediated cytotoxicity against NKG2D ligand-bearing tumors in vitro and in vivo . Applications Tested: The CX5 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.5 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that when using this antibody for staining the secondary must be Biotin anti-rat (cat 13-4813). Other secondaries may give suboptimal staining.

Natural killer (NK) cells are lymphocytes that can mediate lysis of certain tumor cells and virus-infected cells without previous activation. NK cells can regulate specific humoral and cell-mediated immunity, and preferentially express several calcium-dependent (C-type) lectins, which have been implicated in the regulation of NK cell function. The NK gene encodes a member of the NKG2 family, and the encoded transmembrane protein is characterized by a type II membrane orientation (extracellular C terminus) and the presence of a C-type lectin domain. The NKG2 gene family is located within the NK complex, a region that contains several C-type lectin genes preferentially expressed in NK cells.
