Cellular Products
immunoglobulin; monoclonal antibody; against mouse CD40 ligand (CD154, CD40L, gp39)
Comments
Animals were immunized with mouse T cells (Th1).
Spleen cells were fused with NS-1 myeloma cells.
The antibody detects a 39000 dalton protein selectively expressed on activated mouse T cells.
A culture deposited at the ATCC as HB-11048 in May of 1992 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with BM Cycline.
Complete Growth Medium The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium:
  • fetal bovine serum to a final concentration of 10%
  • 0.05 mM 2-mercaptoethanol

Subculturing
Protocol: Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 2 to 3 X 10 exp5 viable cells/ml. Maintain cell density between 1 X 10 exp5 and 1 X 10 exp6 viable cells/ml.
Cryopreservation
Freeze medium: Complete growth medium, 92.5%; DMSO, 7.5%
Storage temperature: liquid nitrogen vapor phase
Culture Conditions
Temperature: 37.0°C
Isotype IgG
Name of Depositor Bristol-Myers Squibb Pharm. Res. Inst.
