I used it about 10 years ago from Laboratories CCD, Paris, France. On the corresponding web page it is not clear it they have discontinued B2 medium or not.
I have found other providers:
...Menezo's B2 medium (Meditech Canada Inc., Montreal, QC, Canada)...
...Menezo's B2 medium (MB2; Pharmascience, Paris, France)...
...Menezo B2 medium (Sevapharma, Prague, Czech Republic)...
Likewise, on the corresponding web pages it is not clear it they have discontinued B2 medium or not.
Do you know a provider of B2 medium (preferably in the EU)?
