SARS-CoV-2, Virus Like Particles (Ha-CoV2) Omicron (BA.2.75): hybrid alpha-pseudovirus for SARS-CoV-2 (Ha-CoV2) for BA.2.75 strain The hybrid alpha-pseudovirus for SARS-CoV-2 (Ha-CoV-2) is a newly developed SARS-CoV-2 virus-like particle (VLP) that encapsulates an alphavirus-derived RNA genome for rapid report expression (luciferase or GFP) in target cells (Hetrick et al., 2022). Different from commonly used S protein pseudotyped lenti- or vesicular stomatitis virus (VSV)-pseudoviruses, Ha-CoV-2 is assembled with all 4 structural proteins (S, M, N, and E) of SARS-CoV-2, and contains a reporter genome derived from an alphavirusbased vector for rapid (6 hours) and robust expression of reporter genes. The alphavirus vector does not contain any of the structural proteins from the authentic virus and the alpha-pseudovirus particles are single-cycle. Formulation & Storage: Store at -80°C. Notes & Usage Guidelines: Spike Mutations: Spike T19I, Spike K147E, Spike W152R, Spike F157L, Spike I210V, Spike V213G, Spike G257S, Spike G339H, Spike S371F, Spike S373P, Spike S375F, Spike T376A, Spike D405N, Spike R408S, Spike K417N, Spike N440K, Spike G446S, Spike N460K, Spike S477N, Spike T478K, Spike E484A, Spike Q498R, Spike N501Y, Spike Y505H, Spike D614G, Spike H655Y, Spike N679K, Spike P681H, Spike N764K, Spike D796Y, Spike Q954H, Spike N969K Size: 25 X 200 µL ~100 wells/96 well plate or 60x Conc. 5 x 100 µL Reporter: Available with Firefly luciferase, GFP, or RFP Intended for research use only, not for human, therapeutic, or diagnostic applications.
