Principle and Interpretation
Complete Supplement Mixture w/o LEU-URA is used as a dropout supplement for all strains of Saccharomyces cerevisiae. Complete Supplement Mixture (CSM) is composed of all the amino acids required for the vigorous growth of Saccharomyces cerevisiae. It also contains uracil. CSM w/o LEU-URA does not contain leucine and uracil. This makes it a double dropout growth medium for yeast cells. It can be mixed with yeast nitrogen base (YNB), ammonium sulphate and an appropriate carbon source (glucose/galactose/raffinose). A leucine and uracil auxotrophic yeast mutant strain cannot grow on this media but a wild-type or a leucine and uracil prototrophic yeast strain can grow.
