a few clinical trials using anti-SARS-CoV-2 immunoglobulins from horses immunized with the entire spike protein or fragments of it in the treatment of patients with COVID-19 are underway. Here, we describe the development of an anti-SARS-CoV-2 equine F(ab′)2immunoglobulin using a newly de...

A single B.1.596 virus from site 1 (hCoV-19/deer/USA/OH-OSU-0340/2021) has a substitution in the spike protein receptor-binding motif (E484D) (Fig. 3c). Both mutations are relatively rare in humans, being found in less than 0.5% of all SARS-CoV-2 viruses sequenced globally. In ...

The trimeric spike (S) protein of SARS-CoV-2 is the primary focus of most vaccine design and development efforts. Due to intrinsic instability typical of class I fusion proteins, S tends to prematurely refold to the post-fusion conformation, compromising

right). This semi-cryptic epitope explains why R1-32 binding promotes RBD to adopt an ‘up’ position. We found that R1-32 was able to bind disulfide-stabilized RBD ‘down’ spikes8with high affinity without dissociating (Fig.3). This process probably disrupted the stabilized spike trimers,...
