Alternative Name CD152 / CTLA4 (CTLA4 Antibody Abstract)
Background The cytolytic T-lymphocyte-associated antigen 4 (CTLA-4) is a member of the Ig superfamily (1) and its extracellular domain exhibits a single Ig V-like region. It was originally identified as a fourth cDNA product, during a search for genes that were thought to be specifically expressed in cytotoxic T lymphocytes (1). CTLA-4 has a molecular weight close to 45 kDa (2). It is mainly expressed as a monomer (4), but may also be expressed as a disulfide-linked homodimer (2,3). CTLA-4 belongs to the CD28 receptor family (4,5).Synonyms: CTLA-4, Cytotoxic T-lymphocyte protein 4, Cytotoxic T-lymphocyte-associated antigen 4
Gene ID 1493
NCBI Accession NP_001032720
UniProt P16410
Research Area CD Antigens, Surface Receptors of Immune Cells
Application Notes Research studies by Microscopy or Flow cytometry, after in vitro activation of T cells with selected stimuli (Concanavalin A, or solid-phase fixed-CD3 + CD28 Mabs stimulation). Research studies on CTLA-4 expression on B cells and on CTLA-4 expression by Immunohistochemistry only on frozen tissue sections. Fluorescence microscopy or Flow cytometry: 2 μg/5x10e5 cells/test. Cytospin or immunohistochemistry on frozen tissue sections: Working concentration is 5-50 μg/mL.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.
