"膜杰作"——四次跨膜蛋白Claudin18.2（HEK293 表达）

Immobilized Human Claudin-18.2 Full Length Protein-VLP (Cat. No. CL2-H52P7) at 5 μg/mL (100 μL/well) can bind Monoclonal Anti-Chimeric Claudin-18.2 Antibody, Human IgG1 with a linear range of 0.2-3 ng/mL (QC tested).
 

Human Claudin-18.2 Full Length Protein-VLP (Cat. No. CL2-H52P7) captured on CM5 Chip via Anti-Claudin-18.2 antibody can bind Anti-Claudin-18.2 antibody with an affinity constant of 0.374 nM as determined in a SPR assay (Biacore T200) (Routinely tested).

2e5 of Anti-Claudin-18.2 CAR-293 cells were stained with 100 μL of 3 μg/mL of Fluorescent Human Claudin-18.2 Full Length Protein-VLP (Cat. No.CL2-HF218) and negative control protein respectively, FITC signals was used to evaluate the binding activity (Routinely tested).

Immobilized Human Claudin-18.2, His,Twin-Strep Tag (Cat. No. CL2-H5587) at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-Chimeric Claudin-18.2 Antibody, Human IgG1 with a linear range of 0.1-2 ng/mL (QC tested).

Anti-Claudin-18.2 mAb captured on CM5 chip via anti-Human IgG (Fc) antibody can bind Human Claudin-18.2, His,Twin-Strep Tag (Cat. No. CL2-H5587) with an affinity constant of 6.72 nM as determined in a SPR assay (in presence of DDM and CHS) (Biacore T200) (Routinely tested).

FACS analysis of cell surface expression of Claudin-18.2 on HEK293/Human Claudin-18.2 Stable Cell Line(Cat. No. CHEK-ATP033). 0.2 million of untransfected HEK293 cells (grey line ) and HEK293/Human Claudin-18.2 stable cells (red line ) were stained with 100 µL of the diluted solution of anti-Claudin-18.2 antibody, Human IgG1 ,washed and then followed by PE anti-Human IgG1 Fc antibody and analyzed with flow cytometry .
