Figure 1From: Visualizing bovine leukemia virus (BLV)-infected cells and measuring BLV proviral loads in the milk of BLV seropositive damsScatter diagrams showing the quantity and quality of DNA in blood and milk. DNA samples were obtained from 2 BLV-negative cattle in Farm 3, 43 BLV-infected cattle without lymphoma in Farms 2–6, and 3 BLV-infected cattle with lymphoma in Farm 1. A The average quantities of genomic DNA in blood and milk samples were 7.9 µg and 6.7 µg, respectively, as determined with a NanoDrop spectrophotometer ND-1000. B The average A260/A280 ratios of genomic DNA in blood and milk were 1.88 and 1.87, respectively, as determined using a NanoDrop spectrophotometer ND-1000. C The threshold cycle values of the blood and milk samples were 22.12 and 22.37, respectively, as indicated with the red bold lines.Back to article page
