Article Title: Optimization of a bovine whole-blood cytokine recall assay for the detection of interferon-gamma and interleukin 10 following stimulation with Coxiella burnetii antigens

Figure Lengend Snippet: Box-and-whisker plot of the distribution of the interleukin 10 (IL10) response to Coxiella burnetii at various dilutions and incubation times in whole blood from 4 cows. Whole blood was stimulated in vitro with C. burnetii phases 1 (P1 CB) and 2 (P2 CB) at concentrations of 5 μg/mL, 0.5 μg/mL, or 0.05 μg/mL and incubated for 24 h (yellow) or 48 h (green). Other stimulants included lipopolysaccharide from rough-form Escherichia coli (LPS), medium (unstimulated control), and pokeweed mitogen (PWM; positive control). Cytokine response was determined using an ELISA. Bold black bars are medians; triangles are means; large dots are outliers. Cytokine response to PWM is presented on the secondary y-axis.
Article Snippet: Microplates (96-well Nunc MaxiSorb) were coated with mouse anti-bovine IL10 antibody (clone CC318; Bio-Rad) at a concentration of 2.5 μg/mL diluted in wash buffer (0.05% Tween 20 in RO water) and incubated at 4°C overnight.
