I have decidet to bought Rhodamine 123 to evaluate mitochondrial activity of a treated green algae. In the research (published) paper where the protocol is described, it is written that I have to dissolve R-123 in 0.1 M PBS.
I would like to know what does exactly means 0.1 M in the case of PBS which is a mix of different salts.
At the moment I have PBS 1X for in vitro human cell culture from Invitrogen and Lonza and PBS tablets from Sigma. But I'm not sure they can be used!
