CHO-SG expresses S-EGFP at cell surface with expected orientation. Non-permeable IFA using the serum (P6 in Tan et al., 2004a) from a recovered SARS patient showed cell surface staining of S-EGFP expressing CHO-SG cells. The control is normal human serum. The green fluorescence seen in the upper panels was from the EGFP tag and the red fluorescence observed in the lower panels was from rhodamine labeled secondary antibody.
