Gene of Interest
OriginSB210 cells were exposed to nitrosoguanidine and crossed to CU329 cells. Self-fertilization (cytogamy) was induced. Self-fertilized progeny were selected for by exploiting the recessiveness of the 2-deoxygalactose-resistance mutation. The cloned progeny were then replicated to rich medium and defined medium at 38°C, and those that grew poorly or not at all in defined medium but well in complex medium, were then tested in defined medium + tyrosine.
