CD8b Monoclonal Antibody (SIDI8BEE), NovaFluor™ Blue 585, eBioscience™
FIGURE: 1 / 2
CD8b Antibody (H057T03B04-A) in Flow
Normal human peripheral blood cells were unstained (left) or stained with CD8b Monoclonal Antibody, NovaFluor Blue 585 (right). All cells were co-stained with CD4 Monoclonal Antibody, eFluor 450 (Product # 48-0047-42). Total viable cells in the lymphocyte gate were used for analysis, as determined by LIVE/DEAD Blue (Product # L34962). Data was acquired on a 5-laser Cytek Aurora and unmixed with autofluorescence extraction.

Product Specific Information
Description: The SIDI8BEE monoclonal antibody reacts with human and rhesus macaque CD8 beta. The CD8b chain associates with the CD8a chain to form the CD8ab heterodimer expressed on the surface of a majority of thymocytes, and on peripheral cytotoxic alpha beta TCR T cells. The CD8 receptor complex binds to MHC class I and plays a role in T cell development and activation of mature T cells. Long been thought to exist either as a heterodimer of the alpha and beta chain or as a homodimer of alpha chains, beta chains have now been shown to homodimerize as well. SIDI8BEE can detect the CD8 beta chain in both the CD8ab heterodimer and the CD8bb homodimer. SIDI8BEE is cross-reactive to human and rhesus macaque CD8b. Other non-human primate species have not been tested.
Each product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer .
Applications Reported: This SIDI8BEE antibody has been reported for use in flow cytometric analysis.
Applications Tested: This SIDI8BEE antibody has been pre-titrated and tested by flow cytometric analysis of human peripheral blood lymphocytes. This can be used at 5 µL (0.8 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.
This NovaFluor conjugate has been updated to ship with CellBlox Plus Blocking Buffer (Cat. No. (C001T06F01)). 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.
NovaFluor 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. Learn more

Target Information
The CD8B antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen, acting as a coreceptor, and the T-cell receptor on the T lymphocyte recognize antigens displayed by an antigen presenting cell (APC) in the context of class I MHC molecules. The functional coreceptor is either a homodimer composed of two alpha chains, or a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 beta chain isoforms. Multiple alternatively spliced transcript variants encoding distinct membrane associated or secreted isoforms have been described. A pseudogene, also located on chromosome 2, has been identified.
