APC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Site-specific conjugation)

相关产品(Related Products): FITC PE Biotin FITC PE APC AF647

抗体来源(Source)

APC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 is produced via site-specific conjugation of APC to Monoclonal Anti-FMC63 Antibody, Mouse IgG1 under optimal conditions with a proprietary technology. We also carry another proclin-containing version of APC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (FM3-AY54A1) 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.

应用(Application)

活性(Bioactivity)-FACS

FMC63 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 APC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Cat. No. FM3-AY54P1) and isotype control antibody respectively. APC signal was used to evaluate the binding activity (QC tested).

Protocol

FMC63 FACS

Non-specificity of APC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Cat. No. FM3-AY54P1) binding to CD3+ cells present in human PBMC. Human PBMCs were simultaneously stained with FITC-labeled anti-CD3 antibody and APC-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (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 APC 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.
