Whitehead SARS-CoV-2 Spike (S) Ectodomain and RBD Libraries
(Pooled Library #157971, #157972, #157973, #168776, #168777, #174293, #174294, #174295, #174296)
These libraries encode mutations to SARS-CoV-2 Spike ectodomain and receptor binding domain (RBD) that were screened in “Francino Urdaniz et al. One-shot identification of SARS-CoV-2 S RBD escape mutants using yeast screening”. The spike ectodomain and RBD sequences are codon optimized for S. cerevisiae.
Spike ectodomain mutations are encoded in the S1 (Library A, B) and S2 (Library C) regions. These libraries were used to screen for mutations that stabilize the ‘up’ prefusion conformation.
The RBD libraries include an N343Q mutation in order to make the RBD aglycosylated when expressed in S. cerevisiae. The RBD sequence has been codon-optimized for yeast expression, and encodes NNK mutations on surface residues. The depositing lab used these libraries to screen for escape mutants from a panel of monoclonal antibodies. The WT, N501Y, and E484Y libraries can be co-transformed with pJS697.

This library is delivered as suspended DNA in a microcentrifuge tube on blue ice. The tube's contents will not necessarily be frozen. For best results, minimize freeze-thaws.
