Measurement of NNT1 levels in conditioned media taken from 7 Human non-small cell lung carcinoma lines, using ab26125 as the capture antibody in a Sandwich ELISA. Conditioned media was collected from all 7 cell lines 48 hours after plating in serum-free media. A 96-well plate was coated with rabbit polyclonal to NNT1 (ab26125 at 1/500 in PBS) overnight at 4°C. 200 µL conditioned media was added to the plates and incubated overnight at 4°C. A mouse monoclonal against NNT1 was added followed by an HRP-conjugated goat anti-mouse secondary antibody. Absorbance was read at 450 nm.
