Biotin Conjugated Human MMP-12 Recombinant Rabbit Monoclonal Antibody [PSH22-93] - Detector

Sandwich ELISA analysis of Human MMP-12 matched pair antibodies

Capture: HA725323, Human MMP-12 Rabbit mAb [PSH22-92]
Detector: HA725324, Human MMP-12 Rabbit mAb [PSH22-93]

Elisa assay was performed by coating wells of a 96-well plate with 50 µl per well of capture antibody (HA725323) 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 MMP-12 protein (HA210856) starting from 1,000 pg/ml to 0 pg/ml and detect antibody (HA725324, Biotin, 0.2 µg/ml) for 1 hour at 30℃ with shaking. Then the plate was washed and incubated with 50 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 MMP-12 in THP-1 cell extract:

Capture: HA725323, Human MMP-12 Rabbit mAb [PSH22-92]
Detector: HA725324, Human MMP-12 Rabbit mAb [PSH22-93]

The concentrations of MMP-12 were measured in duplicates, interpolated from the MMP-12 standard curve and corrected for sample dilution. Undiluted samples are THP-1 cell extract 1 mg/mL. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean MMP-12 concentration was determined to be 41.7 pg/ml in THP-1 cell extract.
