Expression of PRR by bMEC. Quantitative RT-PCR was performed on RNA obtained from bMEC isolated from 5 different cows. ΔCt values (Ct target--Ct for ß-actin gene) for each bMEC are represented on the graph. PCR efficiency was above 90% for all genes and Ct were obtained for an identical fluorescence threshold for all genes.
