Biosafety Level 1

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Storage Conditions liquid nitrogen vapor phase
Derivation
Spleen cells were fused with NS-1 myeloma cells.
Genes Expressed
immunoglobulin; monoclonal antibody; against mouse CD40 ligand (CD154, CD40L, gp39)
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.
