Documentation

Biosafety Icon BSL 1

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Characteristics

Growth properties
Suspension
Derivation
Spleen cells were fused with NS-1 myeloma cells.
Genes expressed
immunoglobulin, monoclonal antibody, against HLA: (A2; B17)

Comments
Animals were immunized with papain solubilized HLA A2 and B17 antigens from the J-Y cell line.
Spleen cells were fused with NS-1 myeloma cells.
Mutation at positions 62 to 66 of the alpha 1 domain of the HLA-A2 molecule results in complete loss of binding of MA2.1.
Tested and found negative for ectromelia virus (mousepox).

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below ­-130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete medium
RPMI medium 1640, 80%; fetal bovine serum, 20%
Handling procedure
Part A. FROZEN CELLS
Vol./Ampule: 1.0 mL.
Recommended Handling Upon Receipt: Initiate culture as soon as possible upon receipt. Thaw by rapid agitation in 37°C water bath. See instructions on back.
Dilute ampule contents with culture medium (see batch data above). Add fresh
medium (depending on cell density) every 2-3 days.
Subculturing procedure
Medium Renewal: Every 2 to 3 days
Cultures can be maintained by addition or replacement of fresh medium. Start cultures at 1 X 10 exp5 cells/ml and maintain between 1 X 10 exp5 and 1 X 10 exp6 cells/ml.
