Recommended storage is -20°C or below.
Protect serum from exposure to light.
It is recommended to avoid freeze-thaw cycles as this can lead to a deterioration in serum qualities.
Ideally, material should be thawed under controlled conditions and re-aliquoted into smaller volumes before re-freezing. It is not recommended to store or refreeze partially used serum as degradation is rapid if microbial contamination occurs. All biological material should be handled as potentially infectious. It is essential that universal precautions should be employed when handling FBS.
