How long does cat serum last? - briefly
Cat serum typically remains stable and effective for up to 1-2 years when stored at -20°C or below, ensuring its integrity for diagnostic or research purposes.
How long does cat serum last? - in detail
The longevity of cat serum depends on several factors, including its intended use, storage conditions, and whether it has been treated with preservatives. When properly stored in a sterile environment at temperatures between 2°C to 8°C (35.6°F to 46.4°F), untreated cat serum can remain viable for up to 7 days. However, if the serum is intended for diagnostic or research purposes, it is often treated with stabilizers or preservatives, which can extend its shelf life to several months when stored at -20°C (-4°F) or lower. Freezing the serum at -80°C (-112°F) can further prolong its usability, potentially preserving it for years without significant degradation. It is crucial to avoid repeated freeze-thaw cycles, as they can compromise the integrity of proteins, antibodies, and other bioactive components within the serum. For immediate use in clinical settings, such as transfusions or therapeutic applications, cat serum should be utilized within 24 to 48 hours of collection to ensure maximum efficacy and safety. Always verify the expiration date and follow specific handling instructions provided by the manufacturer or veterinary guidelines to maintain the serum's quality and effectiveness.
