Organism Rattus norvegicus (B cell); Mus musculus (myeloma), rat (B cell); mouse (myeloma)
Cell Type hybridoma: B lymphocyte
Product Format frozen
Morphology lymphoblast
Culture Properties suspension
Biosafety Level 1
Applications
The LFA-1 antigen is associated with antigen specific T lymphocyte mediated cell killing.
The LFA-1 and Mac-1 antigens are composed of two chains or subunits, alpha and beta.
Tested and found negative for ectromelia virus (mousepox).
Storage Conditions liquid nitrogen vapor phase
Derivation
Spleen cells were fused with P3X63Ag8.653 myeloma cells.
The line was recloned by TA Springer in 1988, and a new seed stock was created at the ATCC.
Genes Expressed
immunoglobulin; monoclonal antibody; against the beta subunit of LFA-1 and Mac-1 (CD18)
Comments
Animals were immunized with mouse cytotoxic T cell glycoproteins.
Spleen cells were fused with P3X63Ag8.653 myeloma cells.
The Mac-1 antigen is a macrophage differentiation antigen associated with type three complement receptor (CR3).
The LFA-1 antigen is associated with antigen specific T lymphocyte mediated cell killing.
The LFA-1 and Mac-1 antigens are composed of two chains or subunits, alpha and beta.
The beta chain of LFA-1 (Leukocyte Function Associated antigen) is immunologically identical to the beta chain of the Mac-1 antigen.
Tested and found negative for ectromelia virus (mousepox).
The line was recloned by TA Springer in 1988, and a new seed stock was created at the ATCC.
