Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material.

Tumorigenic: Yes

Comments: Animals were immunized with rabbit spleen cells.

Spleen cells were fused with P3X63Ag8.653 myeloma cells.

2C4細胞The antibody reacts with an isotypic determinant present on all rabbit Ia molecules, and precipitates polypeptides with molecular weights of 28000, 31000 and 35000 daltons (corresponding to the beta, Ii and alpha chains, respectively).

The antibody is cytotoxic, inhibits mixed lymphocyte reactivity by 80% and inhibits responses to LPS (but not to Con A or PHA).

Tested and found negative for ectromelia virus (mousepox).

Propagation: ATCC complete growth medium: RPMI 1640 medium, 85%; horse serum, 10%; fetal bovine serum, 5%

Subculturing: Medium Renewal: Every 2 to 3 days

Cultures can be maintained by addition or replacement of fresh medium. Start cultures at 2 X 10 exp5 cells/ml and maintain between 1 X 10 exp5 and 1 X 10 exp6 cells/ml.
