AKNOWLEDGEMENT
This study was supported by a Development Fund from the University of
Alabama at Birmingham. Both Drs. Chen Zhang and Wen Jing Law assisted in
analysis of the viral NP protein and infectious SARS-CoV-2 titers. Wild
type SARS-CoV-2 was provided by Dr. Ilya Frolov. Vero E6 TMPRSS2 T2A
ACE2 cells (NR-54970) and different SARS-CoV-2 variants (NR-55461,
NR-55611, NR-56475, NR-56520, NR-56803, NR-58616, and NR-58716) were
obtained from BEI resources. All cell culture work with infectious
SARS-CoV-2 was carried out at Southeastern Biosafety Laboratory
Alabama Birmingham (SEBLAB), a NIH/ NIAID-supported
(UC6AI058599
and 1G20AI167409) Regional Biocontainment Laboratory.
