Hello,
In addition to BSA, these chemically defined lipid concentrate allow us to replace FBS in murine stem cell culture media (CDM). We've been using this lipids for several years. But for several months, we have had batches that precipitate very quickly (a few weeks) and became not good for cell.
Have you had this type of problem with this ref and if so, have you found a solution?
Incriminated batches :
-2658479 exp date : 03/2024
-2620724 exp date :30-05-2024
This is a sensitive product: protect from light and store at 4°C.
We have unsuccessfully tried aliquots in different eppendorf sizes, under ambient atmosphere or nitrogen gas.
Thanks for your suggestions.
