What Samples are Stored in Refrigerators and Freezers?
Histology laboratories frequently store a variety of samples, including tissue specimens, antibodies, enzymes, and other reagents. Tissue samples are often fixed in formalin and then stored in refrigerators at temperatures between 2°C to 8°C to slow down any potential degradation. Freezers, particularly ultra-low temperature freezers that reach -80°C, are used to store sensitive biological samples, such as RNA, DNA, and certain proteins, which require colder conditions to remain stable.
