and international agencies.
Core Diagnostic Product
PrimeStore® MTM is the original Molecular Transport Media for pathogen inactivation, stabilization, and molecular testing sensitivity.
PrimeStore MTM is a globally trusted predicate device, invented and patented in 2007 to safely and efficiently transport RNA/DNA, even under the most challenging conditions. As the original (De Novo) MTM, it was fully optimized to inactivate pathogens and preserve RNA, mRNA & DNA for safer, more efficient, cost-effective sample testing.
This device was a critical component in controlling the Covid-19 pandemic and saving lives around the world. It is being used extensively in the H5N1 outbreak in dairy cows.
Core Vaccine Product
LHNVD-105 is designed to be the most comprehensive universal influenza vaccine ever produced.
Targeting both cellular and humoral immunity, LHNVD-105 is a combination of multiple epitopes across HA, NA, and M2e as well as attached T-cell epitopes. This composite peptide is adjuvanted with the U.S. Army's next generation breakthrough adjuvant AFLQ.
Phase I clinical trials of LHNVD-105 are expected to begin in 2024.
