FcgammaRIIb aAPC/CHO-K1 Cells are engineered to express human FcgammaRIIb and aAPC provided in cryopreserved Cell Propagation Model (CPM) and thaw-and-use formats. The CPM cells can be thawed, propagated and banked for long-term use. These are not reporter cells, and they function to provide activation of the TCR/CD3 complex on effector cells and crosslink anti-CD28 and anti-ICOS agonist antibodies. aAPC/CHO-K1 Cells are engineered to express aAPC provided in cryopreserved Cell Propagation Model (CPM) and thaw-and-use formats.
