Isotopically labelled media for in-vivo enrichment of stable isotopes in E.coli and yeast, optimized to ensure reproducible growth rates, cell density and high yields of heterologous expressed protein.
The quality of our media is controlled by growth test, to guarantee the promised growth rate and optical density. Silantes media are natural products. A slightly different color (e.g. amongst different batches) is absolutely normal for natural products and has nothing to do with the quality.
Other optical densities than OD2 can be ordered on request.
