Specifications

Product Data

• Clone Name: OX-17
• Applications: FC, IHC, IP
• Recommended Dilution: Flow Cytometry.
• Reactivities: Rat
• Host: Mouse
• Isotype: IgG1
• Clonality: Monoclonal
• Immunogen: Rat spleen membrane glycoproteins depleted of Ia-A antigens
  Immunocyte Donor: BALB/c spleen
  Fusion Partner: X63 Ag8.653
• Specificity: This monoclonal antibody recognizes a monomorphic determinant on the α chain of the rat Ia antigen and appears to be the rat homologue of mouse Ia-E. It recognizes the rat Ia product present on B, but not T cells from lymph node or thoracic duct lymph. It does not bind to thymocytes or erythrocytes. The antibody does not cross-react with rat Ia-A or mouse Ia-E antigen, but rabbit antibody raised against the antibody affinity column-purified MRC OX-17 antigen cross-reacted on tissues of mice expressing Ia-E mouse antigen but not on those mouse strains that were Ia-E antigen negative.

  METHOD:
  1. Prepare cell suspension in media A. For cell preparations, deplete the red blood cell population with Lympholyte®-Rat. cell separation medium.
  2. Wash 2 times.
  3. Resuspend cells to 1x10e6 cells in approximately 50 µl media A in a microcentrifuge tube. (i.e. 50 µl of cells resuspended to 2x10e7 cells/ml). The contents of 1 tube represent 1 test.
  4. To each tube add 50 µl of a 1:250 - 1:500 dilution of this Ab.
  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 (FITC Goat anti-mouse IgG (H+L)) at 1:700 dilution.
  9. Incubate 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 phosphate buffered saline. (This stains dead cells by intercalating DNA).
  
  MEDIA:
  A. Phosphate buffered saline (pH 7.2) + 5% normal serum of host species + sodium azide (100 µl of 2 M sodium azide in 100 mls).
  B. Phosphate buffered saline (pH 7.2) + 0.5% bovine serum albumin + sodium azide (100 µl of 2 M sodium azide in 100 mls).
