CD300a
E59/126 IT144 KS153
Mouse monoclonal antibodies raised against human CD300a (E59/126, IT144 and KS153) recognize human CD300a and the antibody KS153 has the ability to interfere with ligand recognition of CD300a. (A) 293T cells were transfected with either a CD300a expressing plasmid or control plasmid for 48h, and subsequently the binding of monoclonal antibodies (E59/126, IT144 an KS153) was assessed by flow cytometry. X-axis of histogram plots indicates fluorescence intensity and empty profile represents appropriate isotype-matched control. (B) Jurkat cells were pretreated with either RPMI, the anti-CD300a antibody KS153 or a non-binding IgM as isotype control for 30 min, and subsequently the binding of the recombinant CD300a-Fc was assessed by flow cytometry. X-axis of histogram plots indicates fluorescence intensity and filled profile represents appropriate isotype-matched control.

The cytolytic response of PRV infected SK cells against primary porcine NK cells. SK cells were mock-infected or infected with WT PRV or kinase-inactive D223A US3 PRV (Becker strain) for 10h and subsequently incubated with IL2-primed primary porcine NK cells at a target:effector ratio of 1:25 for 4h. Viability of target cells was assessed by propidium iodide and flow cytometry, and the percentage NK cell-mediated lysis was calculated. Data represent mean + SEM of three independent experiments.
