Though our biotinylated IGF´s are very stable in solution, we have shipped them in the past on dry ice to ensure maximum activity for our customers. This has increased shipping cost so we have decided to lyophilize our IGF´s. In this form we have kept them for three months at temperatures up to 35 °C without loss of activity. So they can be shipped now without dry ice at reduced freight cost.
For long term storage, we recommend to store the IGF‘s refrigerated after arrival. The reconstituted biotinylated IGF´s are stable for at least one year at a concentration of 20 µg/ml, if kept frozen at -20 °C, and at least for one month at 4 °C. We recommend to aliquot the reconstituted biotinylated IGF´s and to store them at a temperature of – 20 °C.
