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®-H 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 1x10e6 cells, representing 1 test). 4. To each tube, add 50μl of a 0.5-0.2 μg dilution 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. 7. Wash 2 times at 4°C. 8. Add 100 μl of secondary antibody (Streptavidin-FITC) at a 1/500 dilution. 9. Incubate the tubes at 4°C for 30-60 minutes. (It is recommended that the tubes are protected from light since most fluorochromes are light sensitive). 10. Wash 2 times at 4°C in media B. 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 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: Cell Concentration: 1x10e6 cells per test Antibody Concentration Used: 0.5 μg/10e6 cells Isotypic Control: Biotin Rat IgG2a
