抗体来源（Source）
Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) is expressed from human HEK293 cells, which provides higher batch consistency and long term security of supply.
We carry another premium grade FITC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (FM3-FY45G0), produced with the same production process but under more rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. It is designed for cell isolation and cell culture applications in the early preclinical stage.

活性（Bioactivity）-FACS
2e5 of anti-CD19 CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of FITC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Cat. No. FM3-FY45P1) and Isotype control antibody respectively. FITC signal was used to evaluate the binding activity (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.
