best peptone supplier?


our current supplier of peptone switched to a new type and now our OP50 doesn’t grow as good as it used to.
We prefer not to increase the amount of peptone to get the same OP50 yield.

Can anyone recommend a supplier of good bacto peptone for NGM plates ?

We use BD 211820 Bacto Peptone. Our OP50 loves it. Good luck!

The Bacto Peptone that Canman mentions really works quite well, I had the same problem recently and I tried all different Peptones we had and Bacto. I ordered Bacto then, works fine, just to let you know if anyone should also have problems with growing OP50 lawns all of a sudden! :smiley:
