    Monoclonal antibodies that target SARS-CoV-2 with high affinity are valuable for a wide range of biomedical applications involving novel coronavirus disease (COVID-19) diagnosis, treatment, and prophylactic intervention. Strategies for the rapid and reliable isolation of these antibodies, especially potent neutralizing antibodies, are critical toward improved COVID-19 response and informed future response to emergent infectious diseases. In this study, single B cell screening was used to interrogate antibody repertoires of immunized mice and isolate antigen-specific IgG1+memory B cells. Using these methods, high-affinity, potent neutralizing antibodies were identified that target the receptor-binding domain of SARS-CoV-2. Further engineering of the identified moleculesmore »to increase valency resulted in enhanced neutralizing activity. Mechanistic investigation revealed that these antibodies compete with ACE2 for binding to the receptor-binding domain of SARS-CoV-2. These antibodies may warrant further development for urgent COVID-19 applications. Overall, these results highlight the potential of single B cell screening for the rapid and reliable identification of high-affinity, potent neutralizing antibodies for infectious disease applications.

  3. The structural and electronic adaptability ranges of a [VO(SeO 3 )(HSeO 3 )] framework found in organically templated vanadium selenites were determined using a three step approach, informed by cheminformatics descriptors, involving (i) the extraction of the most important reaction parameters from historical reaction data, (ii) a fractional factorial design on those parameters to better explore chemical space and (iii) decision tree construction on organic molecular properties to determine the factors governing framework formation. This process enabled the elucidation of both the structural and electronic adaptability ranges and provided the context to extract chemical understanding from the structural features thatmore »give rise to these respective ranges. This work resulted in the synthesis and structural determination of five new compounds.« less
