Opened plates are sensitive to storage conditions:
- It is essential to immediately close the aluminium envelope after opening.
- Do not throw away the desiccant: the plate should be sealed with the desiccant inside the envelope. This should be carried out rapidly, as the desiccant will quickly absorb humidity and become inactivated after 10-30 minutes.
- The end of the aluminium envelope should be cut with scissors and closed in an air-tight manner along the entire length of the envelope, with scotch tape, for example. (Simply folding-over the edges and/or stapling is insufficient to ensure sealing.). Please refer to the photos on the document Plate storage.pdf
- Store at 5°C ± 3°C.
The majority of ID Screen® kits have a shelf-life of 24 months from the production date.
Please refer to the document Storage conditions.pdf, which indicates the storage conditions (duration and temperature) for each kit component.
We do not indicate an exact expiry date because these sera are very stable over time thanks to their freeze-dried form.
You may consider that they can be kept for up to 10 years from the production date (indicated in the upper right-hand corner of the product sheet). Store freeze-dried at +2° – 26°C.
For information regarding storage in the reconstituted (liquid) form, please refer to the product sheet.
In general, liquid sera should be stored as follows:
- Store at -20°C in aliquots after reconstitution.
- Never freeze/thaw more than 3 times.
- If reconstituted, store at +4°C for up to 2 days.
Once reconstituted, the sera should be aliquoted and stored in air-tight vials (preferably with a twist cap, such as a cryotube). Otherwise, auto-lyophilisation may occur within 6-12 months at -20°C.
