Nitrogen, carbon, trace element, and vitamin source for yeast growth. Supplement with the appropriate DO Mix for selection and propagation of yeast transformants. Drop-out Base With Raffinose and Agar is glucose and galactose free for the reversible repression of galactose-inducible genes. Galactose-inducible genes can be activated by replica plating to galactose plates.

All lots are quality control tested using the appropriate yeast strains and transformants.
