Web1 jan. 2024 · VLPs offer a reliable and realistic model of S-mediated fusion and viral entry events in a BSL-2 setting. Herein, we discuss methods for production, purification, validation, and utilization of SARS-CoV-2 VLPs. Results SARS-CoV-2 VLP production is driven by M coexpression with additional viral proteins Webused TIR-FM to image VLPs collected from the supernatant of cells stably expressing MS2-NLS-GFP, and transiently trans-fected with V1B-MS2, Gag and Gag-mCherry (Fig. S2). Ap-proximately one third of the Gag-mCherry VLPs (33%, n 1,026) were positive for GFP (Fig. 1C). No VLPs had detectable GFP when the viral genome lacked the MS2 stem-loops and

Web26 apr. 2024 · VLPs in the supernatants were concentrated by centrifugation at 100,000× g for 1 h at 4 °C, resuspended in 1 mL of culture medium, and added immediately to 10 6 Raji/CD4 cells overnight. The small aliquots of concentrated VLPs were stored for a subsequent p24 ELISA test. WebCells with attached VLPs were incubated at 37 °C for 1 h to allow for internalization and were then moved to 4 °C for 15 min. Cells were then trypsinized at 4 °C for 30 min to remove non-internalized VLPs. Fluorescence of internalized mCherry VLPs was measured by flow cytometry and mean fluorescence intensity determined using the FlowJo ... the pamper gift card retailers
