Human ULBP1 Recombinant Rabbit Monoclonal Antibody [PSH11-95] - BSA and Azide free (Capture)

Sandwich ELISA analysis of human ULBP1 matched pair antibodies

Capture: HA723406, Human ULBP1 Rabbit mAb [PSH11-95]
Detector: HA723407, Human ULBP1 Rabbit mAb [PSH11-96]

Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA723406) 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 Recombinant Human ULBP1 protein (HA210963) starting from 2500 pg/ml to 0 pg/ml and detect antibody (HA723407, 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 ULBP1 in human cell culture supernatant samples.

Capture: HA723406, Human ULBP1 Rabbit mAb [PSH11-95]
Detector: HA723407, Human ULBP1 Rabbit mAb [PSH11-96]

Interpolated concentration of native ULBP1 was measured in duplicate at different sample concentrations. Undiluted samples were 50% cell supernatant. The interpolated dilution factor corrected values were plotted (mean +/- SD, n=2). The mean ULBP1 concentration was determined to be 831 pg/mL in K562 cell supernatant. There was no detectable signal in HaCaT cell culture supernatant.

Interpolated concentrations of spiked ULBP1 in cell culture media samples.

Capture: HA723406, Human ULBP1 Rabbit mAb [PSH11-95]
Detector: HA723407, Human ULBP1 Rabbit mAb [PSH11-96]

The concentrations of ULBP1 were measured in duplicates, interpolated from the ULBP1 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).
