Applications
The UC10-4F10-11 hybridoma cell line was produced by fusing Sp2/0-Ag14 myeloma cells with spleen cells from an Armenian hamster that had been immunized with the extracellular portion of of murine CTLA-4 fused to a murine IgG2a.
The antibody can be used to detect and quantitate CTLA-4 expression by flow cytometric analysis, and can be used to immunoprecipitate the antigen from CTLA-4 positive cells.
Under conditions of suboptimal T cell receptor (TCR) stimulation, whole antibody or Fab fragments from 4F10 can augment T cell proliferation in allogeneic mixed lymphocyte reactions.
However, when optimal TCR stimulation is present, 4F10 can suppress T cell proliferation.
