Fig. 1.

Reactivities of mAbs raised against MNV-1 and WU20. Plates were coated with equal amounts of MNV-1 or WU20 and hybridoma supernatants were tested for reactivity against MNV-1 (a) or WU20 (b) by ELISA. The mAb A6.2 (100 ng per well) was used as a positive control, whilst isotype controls of IgG2b (IgG) and IgA subclass were used as negative controls. Data are presented as means±sem of at least three independent experiments. The dashed line represents twice the absorbance values at 415 nm (A₄₁₅) for the negative controls and indicates the threshold for a positive signal.
