Edinburgh Minimal Media is a thiamine-free formulation for nmt1 promoter studies for Schizosaccharomyces pombe transformations. The Low Glucose formulation is used for protoplasting and yeast transformations.


Directions per Liter: Dissolve 12.328g in 800-900ml of ddH2O, stirring gently until completely solubilized. Adjust pH of the medium to 0.1-0.3 pH unit below the desired level. Add additional water to bring the solution to 1L. Filter-sterilize using a 0.22 micron membrane filter. Aliquot into sterile containers. Do not autoclave. Contains heat-labile compounds that can be damaged with autoclaving.

Storage and Stability: Store powdered media at RT. Opened bottles should be capped tightly and kept in a dark, low humidity environment. Prepared media should be kept at 4°C and used within a short period of time.

Appearance: White to light tan, homogeneous, free flowing powder

Solubility: Colorless, clear, complete

pH: 6.0 ± 0.7
