Recombinant NIE Antigen from Strongyloides stercoralis

Strongyloides stercoralis is an intestinal nematode endemic that affects an estimated 30 to 100 million people worldwide. Many of these individuals may be asymptomatic for decades. The present invention discloses a NIE recombinant antigen that can be used in improved assays and diagnostics for S. stercoralis infection. The NIE antigen is the only one that is non-cross-reactive with sera from humans with other related filaria infections. The NIE antigen can be utilized as a skin test antigen for immediate hypersensitivity as well as for use in ELISA or other assays.

Sensitive and Economic RNA Virus Detection Using a Novel RNA Preparation Method

DNA or RNA-based diagnostic tests for infectious diseases are critical in modern medicine. The current gold standard for COVID-19 detection is testing SARS-CoV-2 viral RNA by quantitative reverse transcription Polymerase Chain Reaction (RT-qPCR). This method involves patient sample collection with a nasopharyngeal swab, storage of the swab in a universal transport medium during transport to testing site, RNA extraction, and analysis of the extracted RNA sample.
