Database Link	Entrez Gene 12525 Mouse UniProt ID P01731
Synonyms	CD8 alpha chain, CD8A, MAL
Note	Protocol: FLOW CYTOMETRY ANALYSIS: Method: 1. Prepare a cell suspension in media A. For cell preparations, deplete the red blood cell population 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 this suspension to each tube (each tube will then contain 1 x 10e6 cells, representing 1 test). 4. To each tube, add 2.0-1.0 μg of this antibody 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. (It is recommended that the tubes are protected from light, since most fluorochromes are light sensitive.) 7. Wash 2 times at 4°C. 8. Resuspend the cell pellet in 50 μl ice cold media B. 9. Transfer to suitable tubes for flow cytometric analysis containing 15 μl of propidium iodide 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 (100 μl of 2M sodium azide in 100 mls). Results: Tissue Distribution by Flow Cytometry Analysis: Mouse Strain: BALB/c Cell Concentration : 1x10e6 cells per tests Antibody Concentration Used: 2.0 μg/10e6 cells Isotypic Control: FITC Mouse IgM Percentage of cells stained above control: Spleen 10.2% Thymus 66.0%
