What does "sample preservation" mean in biotechnology?

Sample preservation in biotechnology refers to methods employed to maintain the integrity of biological samples over time. This is crucial because biological samples can degrade or undergo changes that may compromise their reliability for analysis or experimentation. Preservation techniques can include refrigeration, freezing, chemical preservation, or dehydration, all aimed at keeping the samples in their original state as much as possible until they are ready to be used.

These preservation methods are essential for ensuring that any biological testing or research conducted with these samples yields accurate and reproducible results. Effectively maintaining the quality of samples allows researchers to draw valid conclusions and maintain the integrity of their scientific work.
