I am currently working with 3T3-L1 cells. From which passage do the cells differentiate best and from when should I rather thaw new cells because the passage is too high? Is there a guideline?
I tried several differentiation protocols and all work from passage 2 on. With one of the protocols I used I got more than 90% differentiated cells up to (including) passage 8. But another differentiation protocol only worked until passage 6.
