Reconstitution and use

Reconstitute the contents of the vial using sterile phosphate-buffered saline (PBS) to a concentration no less than 100 ug/ml and aliquot for future use. (If the initial rehydration is too dilute, activity may be lost due to the non-specific adsorption to the container). The solution can then be further diluted to a working stock solution.

If the product is going to be used for applications requiring absolute asepsis, it's best to filter-sterilize the solution using a sterile and non-pyrogenic 0.2 um membrane before use.

Storage and stability

Upon receiving, store the product at -20oC. After reconstitution, store the working aliquots at 2-8oC for no more than 3 months. For extended storage, aliquot the rehydrated solution (≥100 ug/ml) and freeze at -70oC or -20oC. Avoid repeated freezing and thawing. More dilute solutions stored at -20oC will lose activity faster.
