Anti-CD19 (FMC63) の発現を検出するためのCAR特異的モノクローナル抗体

2e5 of FMC63 scFv-based anti-CD19 CAR-293 cells were stained with 100 µL of the working solution of Monoclonal AntiFMC63 scFv Antibody, Mouse IgG1 (Cat. No. FM3-Y45) and isotype control respectively, washed and then followed by PE anti-mouse IgG1 Antibody and analyzed with flow cytometry (QC tested).

Non-specific binding of Monoclonal Anti-FMC63 scFv Antibody (Cat. No. FM3-Y45) to non-transfected 293 cells was determined by flow cytometry. The data showed that Anti-FMC63 scFv Antibody didn’t bind to non-transfected 293 cells.

Non-specific binding of Monoclonal Anti-FMC63 scFv Antibody (Cat. No. FM3-Y45) to non-transfected human PBMCs was determined by flow cytometry. The data showed that Anti-FMC63 scFv Antibody didn’t bind to non-transfected human PBMCs.

Immobilized FMC63 scFv, His Tag at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-FMC63 scFv Antibody, Mouse IgG1 (Clone Y45) with a linear range of 1-19 ng/mL. Anti-DNP antibody, mouse IgG1 (Cat. No. DNP-M1) was used as an isotype control (QC tested).

ELISA analysis shows that the binding of Human CD19, Fc Tag (Cat. No. CD9-H5251) to FMC63 scFv, His Tag was inhibited by increasing concentration of Monoclonal Anti-FMC63 scFv Antibody, Mouse IgG1 (Clone Y45). The concentration of Human CD19, Fc Tag used is 5 μg/mL (100 μL/well). The IC50 is 0.084 μg/mL (Routinely tested).

Monoclonal Anti-FMC63 scFv Antibody, Mouse IgG1 (Cat. No. FM3-Y45) captured on CM5 chip via anti-mouse antibodies surface can bind FMC63 scFv with an affinity constant of 1.08 nM as determined in a SPR assay.
