PMG - Pombe Minimal Glutamate
From PombEvolution
Jump to navigationJump to searchEdinburgh Minimal Medium Glutamate (EMMG, PMG)
Modification of EMM in which Glutamate is used as a substitute for Ammonium chloride. This medium can be used with antibiotics that do not work on EMM (especially G418). On this medium strains do cross so the medium can also be used to test for mating types. However, it is much richer than the crossing mediums EMM-lowN or EMM-N, so mating takes more time (about 3 days).
If available, use the premixed bottle which contains all ingredients, except nitrogen source (and supplements and agar if needed), which have to be added separately.
