Applications
The antibody reacts with a non-polymorphic Ia like antigen on human cells.
Derivation
Animals were immunized with RPMI 8866 cells. Spleen cells were fused with NS-1 myeloma cells.

immunoglobulin; monoclonal antibody; against human Ia; cytotoxic
Comments
An antibody with similar specificity but not cytotoxic is available (ATCC HB-171, L203).
Tested and found negative for ectromelia virus (mousepox).
Complete Growth Medium The base medium for this cell line is ATCC Hybri-Care Medium, Catalog No. 46-X. Hybri-Care Medium is supplied as a powder and should be reconstituted in 1 L cell culture grade water. To make the complete growth medium, add the following components to the base medium:
  • fetal bovine serum to a final concentration of 10%
  • 1.5 g/L sodium bicarbonate for use with 5% CO2 in air atmosphere.
  • Subculturing
    Cultures can be maintained by addition or replacement of fresh medium. Start cultures at 2 X 105 cells/mL and maintain between 1 X 105 and 1 X 106 cells/mL.

    Medium Renewal: Every 2 to 3 days

    Isotype IgG2a
