Fig. 6From: A sensitive luminescence syncytium induction assay (LuSIA) based on a reporter plasmid containing a mutation in the glucocorticoid response element in the long terminal repeat U3 region of bovine leukemia virusLuSIA using CC81-GREMG with white blood cells (WBCs) from BLV-infected cows. a WBCs (1 × 105 cells) collected from 12 BLV-infected cows and one uninfected cow were cultured with CC81-GREMG for 3 days. b The correlation between provirus copy number and the number of fluorescent syncytia is shown. Provirus loads were assessed by the CoCoMo-qPCR-2 methodBack to article page
