活性（Bioactivity）-ELISA
Immobilized Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251) at 5 μg/mL (100 μL/well) can bind FMC63 scFv, His Tag (Cat. No. CD9-M52Hb) with a linear range of 0.005-0.156 μg/mL (QC tested).
Protocol
背景（Background）
FMC63 is an IgG2a mouse monoclonal antibody specific for CD19, which is a target for the immunotherapy of B lineage leukaemias and lymphomas. FMC63 scFv is the most commonly used ectodomain component of CD19-specific CARs. So far, most of reported CART19 trials contain the anti-CD19 scFv derived from FMC63, including the two FDA-approved CARs Kymriah and Yescarta.
