A majority of thymocytes and a subpopulation of mature T cells and NK cells express CD8a. CD8 binds to MHC class I and through its association with protein tyrosine kinase p56lck plays a role in T-cell development and activation of mature T cells. Preliminary testing indicates that OKT8 and two other mouse anti-human CD8 antibodies (clone RPA-T8, \u003ca href=\"https:\/\/www.thermofisher.com\/antibody\/product\/CD8a-Antibody-clone-RPA-T8-Monoclonal\/414-0088-42\"\u003eProduct # 14-0088\u003c\/a\u003e and clone HIT8a, \u003ca href=\"https:\/\/www.thermofisher.com\/antibody\/product\/CD8a-Antibody-clone-HIT8a-Monoclonal\/14-0089-82\"\u003eProduct # 14-0089\u003c\/a\u003e) do not compete with each other for binding to human peripheral blood leukocytes by flow cytometric analysis, suggesting that they do not bind to similar epitopes or block each other by steric hindrance.\u003c\/p\u003e\u003cp\u003eEach product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer.\u003c\/p\u003e\u003cp\u003eApplications Reported: This OKT8 antibody has been reported for use in flow cytometric analysis.\u003c\/p\u003e\u003cp\u003eApplications Tested: This OKT8 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells. This may be used at (5 µL (0.8 µg)\/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.\u003c\/p\u003e\u003cp\u003eNovaFluor 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.

This buffer contains formulation improvements over CellBlox. CellBlox Plus Blocking Buffer is required for optimal staining with NovaFluor conjugates and should be used in all experiments where NovaFluor conjugates are used. Whenever possible, we recommend adding CellBlox Plus Blocking Buffer to antibody cocktails\/master mixes prior to combining with cells. Add 5 µL per sample (regardless of the number of NovaFluors in your panel) to use the antibody cocktail as intended. For single-color controls, use 5 µL of CellBlox Blocking Buffer per 100 µL of cell sample containing 10^3 to 10^8 cells.\u003c\/p\u003e\u003cp\u003eNovaFluor conjugates are based on Phiton™ technology utilizing novel nucleic acid dye structures that allow for engineered fluorescent signatures with consideration for spillover and spread impacts. \u003ca href=\"https:\/\/www.thermofisher.com\/us\/en\/home\/life-science\/cell-analysis\/flow-cytometry\/novafluor-dyes.html\"\u003eLearn more \u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eExcitation: 494 nm; Emission: 755 nm; Laser: 488 nm (Blue) Laser\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003eFor Research Use Only.
