|Description||CD80 is a member of the Ig superfamily and serves as the ligand for two T cell molecules,CD28 and CTLA4. Interactions between CD28 and CD80 on activated B cells result inenhanced T cell activation. CD80 is rapidly induced on the surface of in vitro activated Bcells, Epstein Barr Virus (EBV) transformed B cell lines, Burkitts lymphoma cell lines,freshly isolated follicular B lymphoma cells, T cells, and monocytes. It is also expressed athigh levels in dendritic cells. It reacts weakly with a small proportion of non activatednormal B cells and with HTLV1 infected T cells. CD80 does not react with peripheralmonocytes, resting and activated normal T cells, T cell lines and T cell clones, nor withmyelomonocytic cell lines.|
|Characteristics||Synonyms: CD28LG, CD28LG1, LAB7, BB1, Activation B7-1 antigen, B7.1, T-lymphocyte activationantigen CD80, CTLA-4 counter-receptor B7.1|
|Specificity||The antibody reacts with in vitro activated normal B cells. Reacts weakly with a small proportion of non-activated normal B cells. Does not react with peripheral monocytes, resting and activated normal T cells, T-cell linesand T-cell clones. Add. Information: The molecular weight of the recognized antigen is 60 kDa.|
|Application Notes||Flow cytometry. Functional study of B cell subpopulations. Fluorescence microscopy or flow cytometry (2 g/5x10e5 cells/test). Immunohistochemistry (1: 20 to 1: 50, suitable on frozen sections or cell smears). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.|
