Immunoelectron microscopy analysis of host proteins in purified PRRSV virions. High purified PRRSV virions were immunogold labeled with antibodies against (A) Beta Actin, (B) Tubulin, (C) Annexin A2, (D) Hsp27, (E) S100 and (F) normal mouse IgG. The labeled virus were then negatively stained by phosphotungstic acid and examined under electron microscope (25,000 × magnification).The number of gold particles per virion is shown below (n = the number of virions counted).
