Hello

This is a problem I encountered repeatedly and I found no answer that made
me really happy. I hope it is not too trivial.

I would like to give the concentration of a substance in a plot title:

5 ug/ml substance

the '5' would be a variable and the ug should be micrograms (with greek
letter mu). It is the mu that causes the problems for me. I failed using
various combinations of paste, expression and bquote. I would be very
grateful if someone could help me (or point me to the solution, which I
might have overlooked).

Thank you very much

Dominik
