Assay: | Pseudotyped virus infection inhibition assay |
Assay Description: | To produce HIV‐luc/SARS pseudotyped virus, 10 µg of HIV‐1 luciferase reporter vector pNL4.3.Luc.E‐R‐luc (HIV‐luc) and 10 µg of codon‐optimized SARS‐CoV S protein expression plasmid (pcTSh) were co‐transfected into 293 T cells by calcium phosphate coprecipitation. The construction of the plasmids have been performeddescribed previously(PMID: 7531918, 15358126). The pseudotyped virus was harvested after 48 h of incubation and purified by ultracentrifugation through a CsCl density gradient at 50,000g for 4 h. The supernatant containing the pseudotyped virus was collected, filtered through a 0.45 µm Millipore‐sized membrane and stored at −80°C until used. To measure luciferase activity, 20‐µl aliquots of the pseudotyped virus were added to 100 µl of Luciferase Assay Reagent (Luciferase Assay Substrate pre‐mixed with Luciferase Assay Buffer, Promega, USA). Luciferase activity was measure 10 s using a Wallac Multilabel 1450 Counter (Perkin‐Elmer, Singapore). |
