Hello,
Has anyone used cholesterol from Alfa Aesar? It is 96% rather than 99% pure cholesterol (3% “other steroids”). We ordered it in lieu of the usual Sigma-Aldrich because Sigma did not have it in stock for a couple of months. GMW is same as Sigma’s, but temp to store is RT, not -20C. How critical is it that the cholesterol be 99% pure for NGM plates?
