About Sierra Molecular Corporation
Sierra Molecular Corporation is the manufacturer of a 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.
Sierra Molecular Corporation has developed strategic partnerships with the academic, public, and private sectors to continually advance the applications of our products. AssayAssure has been utilized in multiple studies and has been cited in more than 60 published, peer-reviewed journal articles.
While there are only a handful of competitors, none of their products maintain samples as long at ambient temperatures (4 to +21 days). No competing products are as flexible on sample matrices, target analytes, and platforms. While AssayAssure is soluble and non-toxic, many competing products are toxic, viscous, and hard to mix.

Our Technology
Sierra Molecular’s AssayAssure® products stabilize human and bacterial cells, viruses, and intracellular targets over extended time periods without freezing or refrigeration. AssayAssure® was designed to inhibit the action of a series of 31 enzyme families known to degrade nucleic acids. Our preservatives negate the effects of nucleases and neutralize substances which inhibit amplification within the samples matrix. This enables extraction and replication of labile RNA and DNA. Even in samples with an extremely low-prevalence of target analyte and in highly inhibitory sample matrices.
