What is the shelf life/expiry date of the ID Screen® ELISA kits? ( 19 April 2013 )

The majority of ID Screen® kits have a shelf-life of 24 months from the production date.

What is the shelf-life of the freeze-dried serum standards (product codes beginning with “MRI”)? ( 23 January 2013 )

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.
