Bioactivity-FACS
 FMC63 FACS

Flow cytometric analysis of Anti-CD19 CAR-293 cells staining with PE-Labeled Monoclonal Anti-FMC63 Antibody, Rabbit IgG1 (1G10) (Cat. No. FM3-PFM721) at 1:50 dilution (2 μL of the antibody stock solution corresponds to labeling of 1e6 cells in a final volume of 100 µL), compared with isotype control antibody. PE signal was used to evaluate the binding activity (QC tested).

 FMC63 FACS

Non-specificity of PE-Labeled Monoclonal Anti-FMC63 Antibody, Rabbit IgG1 (1G10) (Cat. No. FM3-PFM721) binding to CD3+ cells present in human PBMC. Human PBMCs were simultaneously stained with FITC-labeled anti-CD3 antibody and PE-Labeled Monoclonal Anti-FMC63 Antibody, Rabbit IgG1 (1G10) (2 μL of the antibody stock solution corresponds to labeling of 5e5 cells in a final volume of 100 µL), washed and then analyzed with FACS. Both FITC and PE positive signals was used to evaluate the non-specific binding activity to human CD3+ cells (Routinely tested).

  • 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.
