  Results:
  Tissue Distribution by Flow Cytometry Analysis:
  Mouse Strain: BALB/c
  Cell Concentration : 1x10e6 cells per test
  Antibody Concentration Used: 0.5 µg/10e6 cells.
  Isotypic Control: Biotin Mouse IgG2a
  Cell Source: Percentage of cells stained above control
  Thymus: 82.5%
  Spleen: 95.7%
  Lymph Node: 100%
• Reactivities: Mouse
• Host: Mouse
• Isotype: IgG2a
• Clonality: Monoclonal
• Immunogen: BDF splenocytes.
  Donor: C3H spleen.
  Fusion Partner: Sp2/0-Ag14.
• Specificity: This Monoclonal Antibody reacts with both H-2Kd and H-2Dd products. The antibody also cross reacts with Kbsrpq.
  This K-D cross reaction indicates the presence of shared specificities between the two separate H-2 regions.
• Formulation: PBS containing 0.02% Sodium Azide as preservative and EIA grade BSA as a stabilizing protein to bring total protein concentration to 4-5 mg/ml
  Label: Biotin
  State: Liquid purified Ig fraction
• Concentration: 0.1 mg/ml
• Purification: Protein G Chromatography
• Conjugation: Biotin
• Background: The 'classical' MHC Class I molecules are histocompatibility antigens encoded by the H-2 gene complex and consist of heterodimers of highly polymorphic alpha chains noncovalently associated with the invariant beta 2-Microglobulin. (Ref.3,4) These antigens are expressed on most nucleated cells but expression varies on different cell types. MHC Class I molecules present endogenously synthesized peptides to CD8+ T lymphocytes, which are usually cytotoxic T cells. (Ref.5) MHC Class I antigens expressed on thymic epithelial cells regulate the positive and negative selection of CD8+ T cells during T cell ontogeny. (Ref.3,6)

  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 2x107 cells/ml in media A. Add 50 μl of this suspension to each tube (each tube will then contain 1 x 106 cells, representing 1 test).
  4. To each tube, add 0.5–0.2 μg* of AM08081BT-S 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 tubes at 4°C for 30-60 minutes (It is recommended that tubes are protected from 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
  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).
