Description

Description

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 RPA-T8 monoclonal antibody reacts with the human CD8a molecule, an approximately 32-34kDa cell surface receptor expressed either as a heterodimer with the CD8 beta chain (CD8 alpha/beta) or as a homodimer (CD8 alpha/alpha). 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.Applications Reported: This RPA-T8 antibody has been reported for use in flow cytometric analysis.Applications Tested: This RPA-T8 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL per test. A test is defined as the amount 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. For best results when using antibodies conjugated to eVolve™, we recommend a quick spin of the vial before use and avoid touching the bottom of the vial with the pipet tip.Laser/Filter Recommendation: eVolve™ 655 can be optimally excited with laser lines from 325-405 nm, and emits near 655 nm. We recommend using the violet (405 nm) laser line for excitation and a 630LP with a 660/40 bandpass filter, or equivalent, for detection.Fixation Recommendation: Antibodies conjugated to eVolve™ are compatible with eBioscience's fixation and permeabilization buffers.Excitation: 350-635 nm; Emission: 657 nm; Laser: Ultraviolet Laser, Violet LaserStorage and handling: For best results when using antibodies conjugated to eVolve™, we recommend a quick spin of the vial before use and avoid touching the bottom of the vial with the pipet tip.
