  • Patent number: 11726097
    Abstract: Characterization of the binding dynamics at the interface between any two proteins that specifically interact plays a role in myriad biomedical applications. The methods disclosed herein provide for the high-throughput characterization of the specific interaction at the interface between two protein binding partners and the identification of functionally significant mutations of one or both protein binding partners. For example, the methods disclosed herein may be useful for epitope and paratope mapping of an antibody-antigen pair, which is useful for the discovery and development of novel therapies, vaccines, diagnostics, among other biomedical applications.

  • Publication number: 20220362352
    Abstract: The present disclosure relates to methods for restoring or augmenting bactericidal activity of an antibiotic in an organ or tissue in which pulmonary surfactant is present. More specifically, the present disclosure describes that inhibition of antibiotics due to environmental factors, such as the presence of pulmonary surfactant in an organ or tissue such as the respiratory epithelium can be sidestepped or overcome and the effectiveness of the antibiotic in that milieu restored or augmented by co-administration of an antibiotic and a lysin.
