抗体来源（Source）
PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (FM3-PY54A2) is produced via site-specific conjugation of PE to Monoclonal Anti-FMC63 Antibody, Mouse IgG1 under optimal conditions with a proprietary technology.
We carry another premium grade PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (FM3-PY54G0), 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
5e5 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 PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Cat. No. FM3-PY54A2) and isotype control antibody respectively. PE signal was used to evaluate the binding activity (QC tested).
Protocol
Binding activity of the PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 before and after adding 0.03% Proclin was evaluated in the above FACS analysis. The result shows that PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Cat. No. FM3-PY54A2) and PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Cat. No. FM3-HPY53) have the same binding activity against anti-CD19 CAR-293 cells.
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.
