Sierra Molecular Corporation is the manufacturer of an unique, patented pre-analytical ambient temperature biological sample preservation technology. We continue to develop, innovate, test, and refine, both in-house and by independent lab validation. We are headquartered in Incline Village, NV with employees working on the East and West Coast of the United States.

Our patented line of ambient temperature biological sample preservatives includes AssayAssure® Genelock, Multilock, Envirolock, and Hemolock(in Beta testing). AssayAssure® serves as both a biological sample transport medium and an ambient temperature preservative, thus removing the need (and cost) for cold-chain transport. Our sample stabilization technology extends holding times days to weeks compared to non-preserved samples while ensuring accurate results. The stabilization chemistry improves the sensitivity and specificity of assays, including detection and enumeration of low-prevalence targets. Multiple research studies have shown that samples can be refrigerated or frozen after the addition of our biostatic preservatives for long-term storage and reanalysis.
The AssayAssure® product line includes sample collection and transport devices with unique liquid stabilization chemistries. Analysis platforms include microscopy, PCR, real-time PCR, reverse-transcript PCR , Next-Gen Sequencing (NGS), culture, microarrays, and flow cytometry. There is a 70% to 80% cost-savings associated with using the AssayAssure® line of sample collection and transport mediums compared to dry-ice and cool pack shipping.
