Biotin Conjugated Human IL-29 Recombinant Rabbit Monoclonal Antibody [PSH15-10] - Detector

Sandwich ELISA analysis of Human IL-29 matched pair antibodies

Capture: HA723709, Human IL-29 Rabbit mAb [PSH15-09]
Detector: HA723710, Human IL-29 Rabbit mAb [PSH15-10]

Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA723709) diluted in carbonate/bicarbonate buffer, at a concentration of 2 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-29 protein (HA210970) starting from 2,000 pg/ml to 0 pg/ml and detect antibody (HA723710, 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.

Interpolated concentrations of native IL-29 in HUVEC cell culture supernatant untreated or treated with Poly(l:C) and IFNα for 24h.

Detector: HA723710, Human IL-29 Rabbit mAb [PSH15-10]

Interpolated concentration of native IL-29 was measured in duplicate at different sample concentrations and interpolated from the IL-29 standard curves. The interpolated dilution factor corrected values were plotted (mean +/- SD, n=2). The mean IL-29 concentration was determined to be 202 pg/ml in HUVEC treated cell culture supernatant,undetectable in HUVEC untreated cell culture supernatant.

Interpolated concentrations of spiked IL-29 in cell culture media samples.
