PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Site-specific conjugation) (Preservative free) DMF

抗体来源(Source)

PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (FM3-HPY53) is produced via site-specific conjugation of PE to Monoclonal Anti-FMC63 Antibody, Mouse IgG1 under optimal conditions with a proprietary technology. We also carry another proclin-containing version of PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (FM3-PY54A2) produced with the same production process except for proclin, and the proclin-containing product has the same performance and can be stored under 2-8 °C for no less than 12 months after reconstitution.

Besides, 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

FMC63 FACS

5e5 of the 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-HPY53) and PE-Labeled Monoclonal Mouse IgG1 Antibody Isotype Control (Cat. No. DNP-PM1) respectively, PE 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.
