Impact of different blood anticoagulants on the surface expression of CD14 on bovine neutrophils. Whole blood samples obtained from 18 Holstein cows were anticoagulated with: sodium heparin (HEPARIN), sodium citrate (CITRATE) and ethylenediaminetetraacetic acid (EDTA). The percentage of PMN expressing mCD14 (1A) and the mean channel fluorescence intensity (MFI) (1B) was measured. Results for each treatment are the mean from 6 cows. Treatment means with different superscripts are significantly different (p < 0.05) using Scheffe's multiple comparison test.
