How should I reconstitute I1884, Insulin-transferrin-sodium selenite media supplement (ITS Supplement)?
First, make acidified water by adding acetic acid to reduce the pH to approximately 2. To prepare a stock solution, dissolve the contents of the vial in 5 mL sterile, acidified water and swirl to dissolve. Then add 45 mL of sterile water. This prepared solution is at 100X. It is diluted 100 fold (1 ml to 100 ml) to give a 1X final concentration.
What is the stability of I1884, Insulin-transferrin-sodium selenite media supplement (ITS Supplement), in solution?
The stock solution can be frozen in working aliquots. Avoid repeated freeze/thaw cycles. Frozen working aliquots will be stable for at least one year. The solution is stable at 2-8°C for 30 days.
What is the activity of insulin in I1884, Insulin-transferrin-sodium selenite media supplement (ITS Supplement)?
