Improving Molecular Diagnostics Beginning with the Sample

PrimeStore MTM™, (Molecular Transport Medium) is an industry-changing product.

Sample collection and transport of quality nucleic acid is one of the most challenging components of molecular testing and Next-generation sequencing.  Significant time, money and effort are required to get a quality sample to a testing facility. Longhorn has solved the problem with its molecular transport media PrimeStore MTM™, the most comprehensive collection and transport system in the World.

The collection system, PrimeStore MTM™, inactivates microbes including Mycobacterium tuberculosis and every virus ever tested from clinical and environmental specimens and prevents nucleic acid degradation during shipping and storage. DNA/RNA is preserved at ambient temperature (validated at 40°C for 30 days) without refrigeration or freezing and is therefore suitable for all aspects of sample collection to include surveillance and tracking of infectious pathogens in the developing world. 

PrimeStore MTM™ opens up core markets in the Developing World, as well as the Developed World.

Widely used tests such as the Cepheid GeneXpert MTB/RIF assay can be more sensitive when the sample is collected in PrimeStore MTM™.

Sample collection for whole blood (Viral Load Testing, bacterial load testing), viral respiratory samplesbacterial respiratory samples, and tissues in a single product.

Rapid and safe identification can be accomplished with Longhorn's Prime System. This is a molecular diagnostic system, which allows infectious agents to be safely collected, transported and accurately identified (to include asymptomatic patients) within a couple of hours versus days for traditional cultures.  It also allows for both high throughput centralized laboratory testing, and testing in mobile labs without containment capability.

The pathogen specific detection system, PrimeMix®, is an all inclusive, one step PCR reagent mix for point of collection detection. It is temperature stable, requires no mixing, can be loaded on PCR plates and pre-staged at ambient temperatures for high through testing.  It can also be field deployed.
