Murashige and Skoog medium is a widely used plant tissue culture growth medium. M&S Basal Medium contains macronutrients that include high levels of nitrate and organic additives such as agar, sugars, vitamins and growth regulators. Important growth regulators frequently added to M&S include IAA (auxin/morphogen) and the Kinetin (cytokinin/cell division promoter).
Use at a concentration of one ml per liter of prepared medium to achieve the proper final concentration.
Solution contains (mg/ml): 2.0 glycine, 100.0 myo-inositol, 0.50 nicotinic acid, 0.50 pyridoxine hydrochloride, 0.10 thiamine hydrochloride.
Murashige and Skoog medium can be reconstituted from powder or by combining products that are major components of complete M&S medium, such as macronutrient mixtures and vitamin mixtures. Murashige and Skoog Vitamin powder (M3900) can be combined with Murashige and Skoog micro/macro-nutrients to generate basal media which when supplemented with organics, agar, auxins and cytokinins yield complete medium for growth plant tissue culture. The M3900 Solution is a 1000x concentrate which contains (mg/ml): 2.0 glycine, 100.0 myo-inositol, 0.50 nicotinic acid, 0.50 pyridoxine hydrochloride, 0.10 thiamine hydrochloride.
