Immobilized Cetuximab at 2 μg/mL (100 μL/well) can bind Biotinylated Human EGF R, His,Avitag (Cat. No. EGR-H82E3) with a linear range of 2-6 ng/mL (QC tested).
Protocol
Immobilized Human EGF, Tag Free at 10 μg/mL (100 μL/well) can bind Biotinylated Human EGF R, His,Avitag (Cat. No. EGR-H82E3) with a linear range of 0.156-5 μg/mL (Routinely tested).
Protocol
Bioactivity-TR-FRET
In this TR-FRET assay, Streptavidin Protein Europium chelate (for TR-FRET) (Cat. No. FRT-TD09) is used as the Donor and Monoclonal Anti-Human IgG Antibody FA-Labeled (for TR-FRET) (Cat. No. FRT-TA02) is used as the Acceptor. Biotinylated Human EGF R, His,Avitag (Cat. No. EGR-H82E3), at 1.25 ng/well, can bind to the Amivantamab with a linear detection range of 8-0.008 μg/mL (Routinely tested).

Bridging ELISA
Validated with Bispecific Antibody.
Immobilized Human HGF R, His Tag (Cat. No. MET-H5227) at 5 μg/mL, add increasing concentrations of Amivantamab and then add Biotinylated Human EGF R, His,Avitag (Cat. No. EGR-H82E3) at 5 μg/mL. Detection was performed using HRP-conjugated streptavidin with sensitivity of 4.88 ng/mL (Routinely tested).
Evaluation of CAR expression
FACS Analysis of biotinylated EGFR binding cell surface anti-EGFR scFv
Cells were transfected with anti-EGFR scFv and cultured for 3 days. Three days post-transfection, 1e6 cells were stained for anti-EGFR scFv with Biotinylated Human EGFR, His,Avitag (Cat. No. EGR-H82E3) followed by PE-conjugated streptavidin. Flow Cytometry assay shows that Biotinylated Human EGFR, His,Avitag (Cat. No. EGR-H82E3) can bind to cells expressing anti-EGFR scFv. The concentration of EGFR used is 0.8 µg/mL. (Data are kindly provided by Guangzhou Bio-gene Technology Co. Ltd.)
