The technology described is a sophisticated and high-throughput luciferase immunoprecipitation system (LIPS) assay designed to detect antibodies specific to Varicella-zoster virus (VZV) glycoprotein E (gE). By transfecting cells with VZV protein-Renilla luciferase fusion protein constructs and subsequently performing immunoprecipitations with protein A/G beads, this innovative assay enables the quantitative measurement of VZV gE antibody levels in blood serum samples.

This technology represents a significant advancement in the field of rabies prevention, focusing on the development of highly potent rabies-neutralizing monoclonal antibodies (mAbs) for use in postexposure prophylaxis (PEP). With two mAbs, F2 and G5a, displaying exceptional neutralizing titers of 1154 and 3462 International Units (IUs) per milligram, respectively, these antibodies have the potential to offer enhanced protection against rabies when administered alongside rabies vaccines.

This novel therapeutic technology harnesses the power of custom-engineered IgA antibodies to provide localized protection against COVID-19. Unlike conventional antibody treatments that circulate systemically, this innovation is designed for intranasal or inhaled delivery, placing protection directly at the body’s frontline of defense: the respiratory mucosa.

This technology includes monoclonal antibodies (mAb) that specifically and with high affinity bind the final complement components C3dg and C3d (subsequently referred to as C3d), which can be used to kill tumor cells that carry C3d on their cell surface. We show that tumor cells of patients treated with the therapeutic anti-CD20 mAb ofatumumab carry C3d on the cell surface and can bind and be killed by addition of anti-C3 mAbs. In contrast, further addition of more ofatumumab has only minimal effects.
