The technology presented is a breakthrough in the diagnosis of lymphatic filariasis, specifically targeting the B. malayi pathogen. It encompasses a novel soluble antigen extract used in both IgG and IgG4-based ELISA tests, aimed at detecting the presence of the filarial infection. This innovation serves as a cornerstone for a CLIA-certified reference test, established and utilized in Dr. Nutman's laboratory since the late 1980s.

The technology involves the genetic engineering of Respiratory Syncytial Virus (RSV) to express two additional genes, green fluorescent protein (GFP) and Renilla luciferase, from different positions within the viral genome. GFP serves as a visual marker for RSV infection, allowing researchers to monitor and track infected cells using fluorescence microscopy, while luciferase functions as a highly sensitive reporter gene that enables quantitative assessment of viral replication through enzymatic assays.

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.
