By my experience, the optimum concentration of Zeocin for the screening of
the transformant of Chlamy on solid media seems fairly lower than the
concentration Saul Purton suggested (10 ug/mL).  I am just wondering that
the reason might be the difference of the chemical companies they produced
--- Saul said that he obtained from Cayla in France and I purchased it from
