Application Details

Application Notes: Flow Cytometry Analysis (see Protocols).
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.

Protocol: FLOW CYTOMETRY ANALYSIS: Method: 1. Prepare a cell suspension in media A. For cell preparations, deplete the red blood cellpopulation with Lympholyte®-M cell separation medium. 2. Wash 2 times. 3. Resuspend the cells to a concentration of 2x10e7 cells/ml in media A. Add 50 µl of thissuspension to each tube (each tube will then contain 1 x 10e6 cells, representing 1 test). 4. To each tube, add ~1. 0 µg* of this Ab per 10e6 cells. 5. Vortex the tubes to ensure thorough mixing of antibody and cells. 6. Incubate the tubes for 30 minutes at 4°C. 7. Wash 2 times at 4°C. 8. Add 100 µl of secondary antibody (Streptavidin-PE) at a 1: 500 dilution. 9. Incubate tubes at 4°C for 30 - 60 minutes (It is recommended that tubes are protectedfrom light since most fluorochromes are light sensitive). 10. Wash 2 times at 4°C. 11. Resuspend the cell pellet in 50 µl ice cold media B. 12. Transfer to suitable tubes for flow cytometric analysis containing 15 µl of propidiumiodide at 0. 5 mg/ml in PBS. This stains dead cells by intercalating in DNA. Media: A. Phosphate buffered saline (pH 7. 2) + 5% normal serum of host species + sodium azide(100 µl of 2M sodium azide in 100 mls). B. Phosphate buffered saline (pH 7. 2) + 0. 5% Bovine serum albumin + sodium azide (100µl of 2M sodium azide in 100 mls).

Restrictions: For Research Use only

Target Details for CD8B

Target: CD8B (CD8b Molecule (CD8B))

Alternative Name: CD8 beta (CD8B Products)

Synonyms: Cd8b antibody, Ly-3 antibody, Ly-C antibody, Lyt-3 antibody, CD8B1 antibody, LEU2 antibody, LY3 antibody, LYT3 antibody, P37 antibody, Cd8b1 antibody, CD8b molecule antibody, CD8 antigen, beta chain 1 antibody, Cd8b antibody, CD8B antibody, Cd8b1 antibody

Background: The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell to cell interactions within the immune system. The CD8 antigen, acting as a coreceptor, and the T cell receptor on the T lymphocyte recognize antigen 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.Synonyms: CD8B, CD8B1, T-cell surface glycoprotein CD8 beta chain
