- [Pre-print, not peer-reviewed] In vitro experiments show that while the P681H mutation found in the SARS-CoV-2 B.1.1.7 variant was associated with more efficient cleavage of the Spike 1 and Spike 2 (S1/S2) subunits, this did not translate to a significant impact on cell entry or an increase in cell-to- cell spread.
