CD8b, PE-Cyanine7, clone: SIDI8BEE, eBioscience™
Mouse Monoclonal Antibody
Manufacturer: Life Technologies LS25527342
CD8 molecule is composed of two chains termed alpha and beta. CD8 is found on a T cell subset of normal cytotoxic / suppressor cells which make up approximately 20 to 35 % of human peripheral blood lymphocytes. The CD8 antigen is also detected on natural killer cells, 80% of thymocytes, on a subpopulation of 30% of peripheral blood null cells and 15 to 30% of bone marrow cells.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.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 normal human peripheral blood cells. This can be used at 5 μL (0.25 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. Light sensitivity: This tandem dye is sensitive photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 μL cell sample + 100 μL IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.Excitation: 488-561 nm; Emission: 775 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.Filtration: 0.2μm post-manufacturing filtered.
