Isolation of RNA from leukocytes in milk using QIAGEN® RNeasy® Kits - (EN)

One milliliter of milk contains approximately 50,000-200,000 leukocytes (with an average of approximately 100,000 leukocytes). In a BVDV-infected animal up to 1-30% of the leukocytes may be infected with the virus. Each infected leukocyte typically contains 10-10,000 BVDV entities.
