Nourseothricin is a mixturte of Streptothricins C, D, E and F and can be used as selection antibiotic for a broad spectrum of pro- and eukaryotic organisms (i.e. Gram-positive and Gram-negative bacteria, yeast, filamentous fungi, protozoa, microalgae, plants and many more).
Selection of recombinant strains is based on inactivation of Nourseothricin by mono-acetylation of the ß-amino group of the ß-lysine residue by Nourseothricin N-acetyltransferase, the product of the sat1 or nat1 genes.
For selection of recombinant Leishmania strains Nourseothricin is added to the growth medium to a final concentration of 100 μg/ml.
For selection of other species please refer to the product page.
