Biotin Conjugated Human ICAM1 Recombinant Rabbit Monoclonal Antibody [PSH10-16] - Detector

Sandwich ELISA analysis of Human ICAM1 matched pair antibodies

Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA723184) diluted in carbonate/bicarbonate buffer, at a concentration of 5ug/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 ICAM1 protein (HA210857) starting from 4000 pg/ml to 0 pg/ml and detect antibody (HA723186B, 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 ICAM1 in human samples.

Interpolated concentration of native ICAM1 was measured in duplicate at different sample concentrations. Undiluted samples were 0.5% cell supernatant. The interpolated dilution factor corrected values were plotted (mean +/- SD, n=2). The mean ICAM1 concentration was determined to be 392,391 pg/mL in human serum and 1,501 pg/ml in human urine. There was no detectable signal in A549 cell culture supernatant.

Interpolated concentrations of spiked ICAM1 in cell culture media samples.

The concentrations of ICAM1 were measured in duplicates, interpolated from the ICAM1 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).
