Experiment Type: Cytokine analyses of cell culture supernatants

Bovine IFN-γ was measured by using the Bovigam test kit (Prionics, La Vista, NE). A standard curve was generated using recombinant bovine IFN-γ (3.12 to 100 ng/ml; Thermo Scientific, Rockford, IL). Bovine interleukin-10 (IL-10) was quantified by coating MaxiSorp microtiter plates (Nunc, Rochester, NY) with mouse anti-bovine IL-10 in coating buffer (0.05 M carbonate-bicarbonate buffer, pH 9.6 [MCA2110], 2 μg/ml; Serotec, Raleigh, NC) overnight at room temperature (RT). After washing 5 times with PBS containing 1% Tween 80, samples and dilutions of bovine IL-10 standard (0.3125 to 20 ng/ml) (generous gift from Jayne Hope, Compton, United Kingdom) were added to duplicate wells and incubated at RT for 1 h. After being washed, plates were incubated with mouse anti-bovine IL-10-biotin (MCA2111B; Serotec) for 1 h. Plates were washed again and incubated with avidin-horseradish peroxidase (HRP) conjugate (1:800) (PharMingen, San Diego, CA) for 45 min at RT. After another wash cycle, plates were incubated with substrate solution (40 mM ABTS [2,2′-azino-diethylbenzthiozoline-6-sulfonic acid]; US Biological, Swampscott, MA). Color development was quantified after 30 min by measuring absorbance at 405 nm with a Wallac Victor 1420 multilabel counter enzyme-linked immunosorbent assay (ELISA) plate reader (Perkin-Elmer, Gaithersburg, MD). To quantify bovine IL-4 in culture supernatants, plates were coated with mouse anti-bovine IL-4 (clone CC313, 5 μg/ml; Serotec) in 0.05 M carbonate-bicarbonate buffer and incubated overnight at 4°C. After being washed, plates were blocked with PBS containing 1% bovine serum albumin (BSA) and 0.05% Tween 20 for 1 h at RT. After being washed, samples and dilutions of the standard (recombinant bovine IL-4 [PBP006], 15.6 to 2,000 pg/ml; Serotec) were incubated for 1 h at RT, followed by incubation with mouse anti-bovine IL-4-biotin antibody (clone CC314, 2.5 μg/ml; Serotec) for 1 h at RT, streptavidin-horseradish peroxidase (1:1,000; GE Healthcare, Piscataway, NJ) for 45 min at RT, and then ABTS substrate (US Biological) for 1 h at RT, followed by measuring absorbance at 405 nm. Bovine IL-12 was measured by ELISA after coating plates with mouse anti-bovine IL-12 antibody (MCA1782EL, 8 μg/ml; Serotec) diluted in 0.05 M carbonate-bicarbonate buffer overnight at 4°C. Plates were then blocked with 1% BSA overnight at 4°C, followed by the addition of samples and standard dilutions (55 to 1,500 U/ml; kind gift from Jayne Hope, Compton, United Kingdom), and were incubated for 1 h at RT. This was followed by incubation with biotinylated anti-bovine IL-12 (MCA2173B, 1 μg/ml; Serotec) for 1 h at RT, incubation with streptavidin-horseradish peroxidase (1:800) and ABTS substrate for 1 h at RT, and then measurement of absorbance at 405 nm.

1. There were no discernible effects due to vaccination or in vitro stimulation of cells on the secretion of IL-12 (data not shown). 2. Robust IFN-γ responses were observed in vaccinated calves, but secretion of IL-4, IL-10, and IL-12 was not markedly affected by vaccination.
