Thermo Fisher Scientific Preservation Matrix Offers More Efficient and Reliable Sample Storage

Thermo Scientific Bioservative Protects Valuable Cells and Biomolecules against Degradation without Refrigeration

Thermo Fisher Scientific Inc., the world leader in serving science, today announced the release of Thermo Scientific Bioservative, a sample preservation matrix that does not require refrigeration. Bioservative™ ensures the cell viability of microbiological samples for up to seven days and delays the breakdown of RNA, DNA and peptides within a sample for up to 26 days. Bacterial cells taken from the sampling environment and stored in Bioservative are held in a state of suspended metabolic activity, stopping continued growth and allowing accurate analysis of the bacterial content. The matrix also stabilizes the sample pH, preventing cell death and pH hydrolysis of biological molecules. Preservation of samples in this way protects against freeze-thaw damage, enabling convenient aliquoting from batch materials in long term storage.

Pharmaceutical, biomolecular, environmental, bioremediation and hygiene samples often contain fragile constituents that degrade rapidly if stored incorrectly. And getting samples into cold storage quickly enough to prevent this breakdown presents significant logistical challenges. Maintaining the integrity of sensitive sample components is critical to effective downstream processing and measurement. Additionally, bacteria collected within microbiological samples continue to replicate after the sample is taken, potentially destroying the sample with biased overgrowth and cell lysis. The Thermo Scientific Bioservative storage matrix provides the support necessary for the samples after they have been collected, boosting the efficacy of downstream analysis and generating more reliable data from the available material.
