Influence of time of harvest on negative controls and infected cells. Immunocytometric detection MDCK cells stained with antibodies against influenza A virus M1 and NP: Negative controls: uninfected cells (I), mock-infected stained cells, harvested 2 h p.i. (II); infected cells: equine influenza A virus-infected, harvested 18 h p.i. (III), equine influenza A virus-infected, harvested 6 h p.i. (IV).
