At what temperatures do Cryoniss store biological samples?

At Cryoniss, we can accommodate storage of biological samples from ambient, +4˚C, -20˚C, -80˚C and -196˚C (vapour phase liquid nitrogen) in our world-class facilities. The purpose of biopreservation is to maintain the integrity of biological samples over time with the ability to recover them on demand in the future for further research.

The temperature at which samples are stored depends greatly on how the samples have been preserved against degradation of the samples and infection from contaminants. Scientists use multiple different methods to protect the samples and depending upon the end-user assay and target molecule determines how these samples are prepared and ultimately stored.

For example, dimethyl sulfoxide used as a cryopreservant for storage of live cell lines to be recovered from -196 ˚C is a different requirement from storage of formalin-fixed paraffin embedded tissues that can be stored at room temperature. However, if the analysis in the future of the FFPE samples is for RNA purposes then it is better to store them at +4 ˚C for long-term.
