Abstract: Disclosed herein are methods for the generation of highly accurate nucleic acid libraries encoding for predetermined variants of a nucleic acid sequence. Further provided herein are method for identifying variant species with increased or decreased activities, with applications in regulating biological functions and the design of therapeutics for treatment or reduction of disease.

Abstract: Provided herein are methods and compositions relating to libraries of optimized antibodies (e.g., multispecific antibodies) having nucleic acids encoding for an antibody comprising modified sequences. Libraries described herein comprise nucleic acids encoding SARS-CoV-2 or ACE2 antibodies.

Abstract: Provided herein are methods and compositions relating to libraries of optimized antibodies having nucleic acids encoding for an antibody comprising modified sequences. Libraries described herein comprise nucleic acids encoding SARS-CoV-2 or ACE2 antibodies. Further described herein are protein libraries generated when the nucleic acid libraries are translated. Further described herein are cell libraries expressing variegated nucleic acid libraries described herein.
