Leading development and innovation in molecular testing

Since 2006, they have been designing and developing products in preparation for the universal influence of a pandemic. More than 15 years of continued investment and research have led them to some of the largest breakthroughs in the testing space. Their unique diagnostic solutions thrive in a wide variety of environments, helping to diagnose and treat infectious diseases such as Influenza, SARS-CoV-2, Monkeypox, and Mycobacterium Tuberculosis (MTB).
The strength and scalability of their products has allowed them to grow into a large, competitive operation in a matter of weeks. Whereas they could previously produce 50-100k tubes of PrimeStore MTM per month, during the COVID-19 pandemic weekly shipments have exceeded two million tubes.

PrimeStore® MTM

Longhorn Vaccines and Diagnostics designed and developed the patented, FDA cleared inactivating transport medium PrimeStore® MTM for both RNA and DNA.  Proven to completely inactivate viruses and challenging, high consequence pathogens/foreign animal diseases in different sample matrices with nucleic acid transport stability even at high temperatures, providing high quality nucleic acid for RT-PCR and Sequencing.  Remember not all MTMs/ITMs are the same. PrimeStore® MTM consistently outperforms other medias with proven inactivation by multiple national reference laboratories.

PrimeStore® MTM

Self-contained, ready-to-use system that allows for the stabilisation and safe transport of clinical samples at ambient temperature from the collection site to the laboratory.
