Subcellular localization of cyclophilin A (CyPA), HAb18G/CD147, and antagonistic peptide (AP)–9 on severe acute respiratory syndrome coronavirus (SARS-CoV)–infected 293 cells. A Gold particles representing CyPA (arrow) located on the virus surface in a cluster or around the virus. B Gold particles representing CD147 (arrow) located on the infected cell surface, across the membrane, or on the unit membrane in cytoplasm (especially on the membrane of endoplasmic reticulum) in cluster. C Gold colloid double labeling. Gold colloid particles of 2 different sizes that indicated AP-9 (20 nm) and HAb18G/CD147 (10 nm), respectively, were located on the same site (arrow)
