Figure 1From: Highly specific fiber optic immunosensor coupled with immunomagnetic separation for detection of low levels of Listeria monocytogenes and L. ivanoviiIndirect ELISA using (a) MAbs 2D12, 3B7, 4E4, and 3F8 or (b) MAb-3F8 against different bacterial strains and purified rInlA. Several 96-well microtiter plates were coated with live bacteria (~1 × 109 CFU/mL) for 16 h at 4 °C. Data are the mean ± SD of 3 independent assays performed in duplicate.Back to article page
