Sandwich ELISA analysis of mouse CCL22 matched pair antibodies Capture: HA723780, Mouse MDC/CCL22 Rabbit mAb [PSH15-76] Detector: HA723781, Mouse MDC/CCL22 Rabbit mAb [PSH15-77] Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody MR240604-AA1341-1-1H9 or MR240604-AA1341-1-1C11 diluted in carbonate/bicarbonate buffer, at a concentration of 2ug/ml overnight at 4℃. Wells of the plate were washed, blocked with 150 µl 0.05% tween-20 1%BSA blocking buffer, and incubated with serial diluted mouse CCL22 protein (HA211072) starting from 500 pg/ml to 0 pg/ml and detect antibody MR240604-AA1341-1-1E2 -Biotin (0.2 µg/ml) for 1 hour at 30℃ with shaking. Then the plate was washed and incubated with 100 µl per well of SA-HRP for 0.5 hour at 30℃ with shaking. Detection was performed using an Ultra TMB Substrate for 10 minutes at room temperature in the dark. The reaction was stopped with sulfuric acid and absorbances were read on a spectrophotometer at 450 nm.
