CD4 Monoclonal Antibody (SK3 (SK-3)), NovaFluor™ Blue 660-120S, eBioscience™, Invitrogen™

Description

The SK3 monoclonal antibody reacts with human CD4, a 59-kDa cell surface receptor expressed by a majority of thymocytes, a subpopulation of mature T helper cells, and at low levels on monocytes. CD4 is a receptor for the human immunodeficiency virus (HIV). SK3 blocks HIV binding and mixed lymphocyte reaction. The SK3 and RPA-T4 monoclonal antibodies do not cross-block binding, suggesting recognition of distinct epitopes.
Applications Reported: This SK3 (SK-3) antibody has been reported for use in flow cytometric analysis.
Applications Tested: This SK3 (SK-3) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 2 μL (0.1 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.
NovaFluor dyes are not compatible with DNA intercalating viability dyes. Do not use viability dyes such as propidium iodide, 7-actinomycin D (7-AAD) and DAPI. Invitrogen LIVE/DEAD Fixable Dead Cell stains are recommended for use with NovaFluor dyes.
When using more than one NovaFluor dye, CellBlox Monocyte and Macrophage Blocking Buffer may be used to block non-specific binding of dyes to monocytes.
