| Application Notes | For binding ELISA, 384-well ELISA plates were coated with 2 μg/mL of antigens in 0.1 M sodium bicarbonate overnight at 4_x005f_x0004_°C. Plates were washed with PBS + 0.05% Tween 20 and blocked with blocked with assay diluent at room temperature for 1 h. Purified mAb samples in 3-fold serial dilutions in assay diluent starting at 100 mg/mL, or un-diluted transfection supernatant were added and incubated for 1 hour, followed by washing with PBS-0.1% Tween 20. HRP-conjugated goat anti-human IgG secondary Ab was diluted to 1:10,000 and incubated at room temperature for 1 h. These plates were washed four times and developed with tetramethylbenzidine substrate. The reaction was stopped with 1 M HCl, and optical density at 450 nm was determined. |
