Storage instructions

In many cases it is not necessary to keep the goods cooled during shipping. However, after you receive the goods it is vital to observe the storage recommendations stipulated in the data sheet.

Lyophilized antibodies/proteins are very stable and only become sensitive to storage conditions after dissolving. They can be stored unopened at ambient temperature for many days, but should be stored at 2-8°C minimum. Long-term storage of unopened lyophilizates (years) should be at a minimum of -20°C.

Protein/antibody solutions must be stored at a minimum of 2-8° C or -20° C.

Important: Repeated freezing and thawing of antibody/protein solutions must be strictly avoided as this may result in impairment of functionality. If antibody/protein solutions stored at 2-8°C are not used within a few weeks, they must be aliquoted for long-term storage and frozen at -20° C or -80° C. Aliquotes should be at least 50µl in order to avoid loss by adsorbtion. For this purpose it can be helpful to pre-dilute the protein/antibody solution (e.g. 1:5 or 1:10 in PBS/5% BSA) for subsequent aliquotation. After thawing solutions once for use, do not freeze them again. An alternative option is liquid storage of antibody/protein solutions in the presence of glycerol at -20°C: For this purpose dilute the solution 1:1 with highly purified glycerol as anti-freeze. This inhibits formation of damaging ice cristals and the solution remains liquid (anti-freeze is not suitable for temperatures of -80°C).
