Products
PrimeStore MTM
A molecular transport medium formulated to inactivate pathogens on contact and preserve nucleic acids at ambient temperature for downstream molecular testing.
Salorn STM
A guanidine-free, virucidal and bacteriostatic sample collection device intended for antigen testing workflows.
PrimeScreen MTB
An oral triage screening kit intended to detect Mycobacterium tuberculosis DNA from oral swabs to identify individuals for further clinical evaluation.
PrimeSeqMDR
An optimized reagent blend (primers, buffers, enzymes) for full-length amplification of tuberculosis resistance genes to support molecular resistance profiling.
PrimeXtract
A spin column-based total nucleic extraction system designed for efficient and sensitive RNA purification from clinical specimens.
Composite peptide vaccine candidates (including universal influenza and sepsis-focused designs)
Vaccine candidates built on a composite peptide platform selecting conserved viral or bacterial epitopes and combined with adjuvants to generate broad immune responses; includes programs targeting influenza (universal vaccine) and multivalent bacterial targets for sepsis prevention.
