iFluor® A7 SE

AAT Bioquest's iFluor® A7 dye was developed for labeling proteins, particularly antibodies. iFluor® A7 has a fluorescence excitation and emission maxima of ~762 nm and ~782 nm respectively, with good photostability. The APC-iFluor® A7 tandem is an excellent replacement for BD's APC-H7. Our in-house comparable studies indicated that the APC-iFluor® A7 tandem demonstrated comparable fluorescence properties to the APC-H7 tandem. The A7 SE dye is reasonably stable and shows good reactivity and selectivity with proteins.

<p>Human peripheral blood lymphocytes were stained with 5 uL (0.25 ug) APC-A7 Anti-Human HLA-DR (solid line) or 0.25 ug APC-A7 Mouse IgG2a isotype control (dashed line). The L243 antibody reacts with a member of the human MHC Class II antigens, HLA-DR. The HLA-DR antigen is expressed on B lymphocytes, activated T lymphocytes, activated NK cells, monocytes, macrophages, other antigen presenting cells and progenitor cells. The L243 antibody is specific to an epitope on the alpha subunit of the heterodimeric HLA-DR protein and binds a different epitope than the LN3 antibody clone. It does not cross-react with HLA-DP or HLA-DQ. This antibody is reported to be cross-reactive with non-human primates including Chimpanzee, Cynomolgus, Rhesus and Baboon. Please choose the appropriate format for each application.</p>
