Background	DAF is one of several membrane proteins that prevent host cells from homologous complement attack. The two mouse DAF isoforms are effective against rat complement, but not against human and guinea pig complement. GPI-DAF is expressed on erythrocytes, spleen and testis while TM-DAF (transmembrane-DAF) is expressed only in testis. Both types of DAF transfectants avoided C3 deposition more successfully than non-transfectant cells.
Synonyms	CR; CROM; DAF; TC
Note	Protocol: Flow Cytometry Analysis: Method: 1. Prepare 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 1x10e6 cells, representing 1 test). 4. To each tube, add 1.0 µg of AM31864BT-N per 1x10e6 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: Mouse Strain: Balb/c. Cell Concentration : 1x10e6 cells per test. Antibody Concentration Used: 0.2 μg/10e6 cells. Isotypic Control: Armenian Hamster IgG-Biotin.
