SEC-MALS
The purity of Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Cat. No. FM3-Y45A1) is more than 95% and the molecular weight of this protein is around 140-160kDa verified by SEC-MALS.
Report
活性（Bioactivity）-ELISA
Immobilized FMC63 scFv, His Tag at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Cat. No. FM3-Y45A1) with a linear range of 1-19 ng/mL. Mouse IgG1 Kappa Isotype Control (mAb) (Cat. No. DNP-M1) was used as an isotype control (QC tested).
Protocol
ELISA analysis shows that the binding of Human CD19, Fc Tag (Cat. No. CD9-H5251) to FMC63 scFv, His Tag (Cat. No. CD9-M52Hb) was inhibited by increasing concentration of Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Cat. No. FM3-Y45A1). The concentration of Human CD19, Fc Tag used is 5 μg/mL (100 μL/well). The IC50 is 0.084 μg/mL (Routinely tested).
Protocol
活性（Bioactivity）-SPR
Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Cat. No. FM3-Y45A1) captured on CM5 chip via anti-mouse antibodies surface can bind FMC63 scFv with an affinity constant of 1.08 nM as determined in a SPR assay (Routinely 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.
