Figure 2From: Preferential use of Siglec-1 or Siglec-10 by type 1 and type 2 PRRSV strains to infect PK15S1–CD163 and PK15S10–CD163 cellsDetection of receptor expression in PK15, PK15S1–CD163 and PK15S10–CD163 cell lines. Expression of receptors (Siglec-1, Sigle-10 and CD163) in PK15, PK15S1–CD163 and PK15S10–CD163 were analyzed by confocal microscopy (left) and flow cytometry (right). Scale bar: 25 µm.Back to article page
