Thermo Fisher product holds bacterial samples in a state of suspended metabolic activity

Thermo Scientific has introduced a sample preservation matrix that does not require refrigeration.

According to the US supplier to the pharmaceutical industry 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.

In addition, the matrix stabilises the sample pH, preventing cell death and pH hydrolysis of biological molecules. Preservation of samples in this way is said to protect against freeze-thaw damage, enabling convenient aliquoting from batch materials in long term storage.

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.
