I have the method for total antioxidant capacity assay kit no-ab65329. I can’t see any info about freezer storage temps. What temp should serum be stored at. Also we’ll have samples being transported from South Africa so if they are transported on dry ice is this sufficient?

Thank you for your enquiry.
Generally, serum can be stored at -20°C or at -70°. Freeze the tubes of serum rapidly, and store the aliquots protected from light. After thawing a tube, do not refreeze the serum unless you intend to store it for an extended period of time.
Serum stored at -20°C should be used within 6-12 months of preparation, but serum stored at -70°C may be kept longer. Normally, serum stored in a refrigerator (2-8°C) should be used within 2 weeks.
If you need any further assistance in the future, please do not hesitate to contact me.
