I've noticed that when thawing long-frozen samples (3-4 months at -20 C), most of the SARS-CoV-2 virus does not remain intact, but that the surrogate appears to. Has anyone else noticed this?
BRSV is labile in it is infectivity and characterizrd by lack of neurominidasr which may cause which make BRSV less suscp tible toRNA degredation than SARS_Cov2.Thanks
