PrimeStore MTM should not be used with the Hologic Panther System due to a disinfecting step involving bleach that is specific to that platform. PrimeStore MTM, like most lysis buffers and nucleic acid purification reagents, contains Guanidine. Bleach and guanidine create cyanide gas which is why most molecular lab protocols use ethanol based decontamination and cleaning solutions rather than bleach. To take advantage of the microbial inactivation and RNA stabilization qualities of PrimeStore MTM, users can safely test on a wide variety of high throughput platforms from Roche, Thermo Fisher, Abbott, Siemens, Luminex, BioRad, PSS, Promega, and BioMerieux, as well as the Cepheid GeneXpert point of care platform.
LHNVD is in close communication with the FEMA/HHS about supply capacity expansion. We are working with buyers to optimize tube selection to match available swabs and to fit into existing automation systems. For specific questions email firstname.lastname@example.org.
Bleach should be avoided for clean up for most molecular tests and nearly all extraction reagents contain guanidine. Sample collection devices that claim inactivation/ and or stabilization that list their ingredients as proprietary should be considered to have Guanidine and other potentially reactive chemicals.
PrimeStore MTM is the only media on the FDA preferred list that inactivates SARS-CoV-2 during the collection and transit stage.
