Detection of PRRSV receptors in SJPL cell line by immunofluorescence. The IFA was done using specific antibodies directed against CD151, CD163 and Sialoadhesin proteins in SJPL, PAM and MARC-145 cells. Negative control was obtained without primary antibody exposition. As an example of results, the negative controls illustrated are the FITC conjugated anti-mouse. All cell nuclei were stained with DAPI. Cells were visualized under UV exposition. Scale bar = 100 μm.
