Target
Function
Associates with IL12B to form the IL-23 interleukin, an heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 may constitute with IL-17 an acute response to infection in peripheral tissues. IL-23 binds to an heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis.

Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA721933) diluted in carbonate/bicarbonate buffer, at a concentration of 4 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 Human IL-23 protein (HA210909) starting from 3000 pg/ml to 0 pg/ml and detect antibody (HA721934, 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. -
Conditioned media was harvested after 16 hours. IL-23 was measured in 100% unstimulated and LPS stimulated THP-1 supernatant. The concentrations of IL-23 were interpolated from the IL-23 standard curves. The mean IL-23 concentration was determined to be 1407 pg/mL in LPS stimulated THP-1 supernatant. There was no detectable signal in unstimulated supernatant.
