Stability and Storage

Bioactive chemical stability and storage

Due to the novelty of many of our products, information concerning product stability has rarely been reported and in most cases we can only offer a general guide. When information is known we do our best to publish this in the catalog or on the data sheets that accompany our products. Our standard storage recommendations are as follows:

Solid: Provided storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 6 months.

Solution: We recommend that stock solutions, once prepared, are stored as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Wherever possible, solutions should be made up and used on the same day. Before use, and prior to opening the vial, it is recommended that the product be allowed to stand at room temperature for at least 60 minutes.

In all cases refer to the datasheet as conditions vary for different products.

Peptide stability and storage

Peptides are provided in lyophilized form and should be stored dessicated at -20°C. Long-term storage of peptides in solution is not recommended.

Short periods of high temperature

Short periods at higher temperatures than recommended (periods < 1 week), such as can occur during shipping, will not significantly affect product life or efficacy.

For further information, please visit our temperature during shipping support page.

Tocrisolve stability and storage

Tocrisolve products must not be stored at -20°C as freezing has an adverse effect on the stability of the formulation. Provided that the vial is kept tightly sealed, protected from exposure to light and stored at +4°C, the product should be stable for 1 month from the date of dispatch.
