Sandwich ELISA analysis of mouse RANKL matched pair antibodies
Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA722922) diluted in carbonate/bicarbonate buffer, at a concentration of 5 µg/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 Recombinant Mouse RANKL protein (HA210558) starting from 8000 pg/ml to 0 pg/ml and detect antibody (HA722924, 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.

☑ Cell treatment (CT)
Interpolated concentrations of native RANKL in mouse spleen cell culture supernatant treated or untreated with concanavalin A for 3days .
Interpolated concentration of native RANKL was measured in duplicate at different sample concentrations and interpolated from the RANKL standard curves. Undiluted samples were 100% cell supernatant. The interpolated dilution factor corrected values were plotted (mean +/- SD, n=2). The mean RANKL concentration was determined to be 3,251 pg/mL in neat mouse spleen cell treated supernatant, undetectable in untreated mouse spleen cell supernatant.

Interpolated concentrations of spiked RANKL in human cell culture media samples.
The concentrations of RANKL were measured in duplicates, interpolated from the RANKL standard curves and corrected for sample dilution. Undiluted samples are as follows: cell culture media 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).
