抗体来源（Source）
Monoclonal Anti-FMC63 Antibody, Rabbit IgG (1G10) is a rabbit monoclonal antibody recombinantly expressed from human 293 cells (HEK293), which provides higher batch consistency and long term security of supply. It shows superior performance in flow cytometry assays with higher affinity and better specificity.

活性（Bioactivity）-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).
Protocol
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 (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.
