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.
- Quantity: 10 µg or 20 µg
- Description: Biotin- Leu24 IGF-1 is prepared by a selective biotinylation procedure. As in the non-biotinylated analog, binding to the receptor is strongly reduced. Binding to IGFBP-1 to -5 is not substantially affected.
- Storage: Store refrigerated upon arrival. The product is stable at 4 °C for at least two years. Reconstitute with 0.5 ml water and store aliquots frozen at – 20 °C. Avoid repeated freeze-thawing cycles.
