Components shown as g/liter
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 is glucose and galactose free for the reversible repression of galactose inducible genes that is relieved by the addition of galactose to 4% or the resuspension of cells in galactose media.
All lots are quality control tested using the appropriate yeast strains and transformants.
