How long can frozen human serum be stored?

Although it is impossible to claim stability data for every possible application and use, for human serum AB we conservatively estimate that if this product is stored properly at -20ºC, it can be used up to 5 years from the date of manufacture without any decrease in product performance. Storage at any other temperature may affect results. However, once thawed and opened for use, it is not recommended to store or refreeze partially used serum as degradation is rapid if microbial contamination occurs.
