General description

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).

Application

Murashige and Skoog medium has been used in plant tissue culture medium for plant transformation study.[1][2]

Formula variant

With the macro- and micronutrients, and vitamins as described by Murashige and Skoog (1962).

Media Formulation

Quantity

Formulated to contain 4.4 grams of powder per liter of medium.

Preparation Note

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 medium (M5519) contains the micronutrients and vitamins of the original classic formulation. It can be supplemented with sucrose, agar, auxins (IAA) and cytokinins (Kinetin) to generate a complete medium for growth plant tissue culture.

Questions

1–10 of 11 Questions  

  1. How do I prepare this medium?

    1 answer

    1. The preparation instructions for this product are as follows:
      1. Using a container twice the size of the desired final volume, measure out ~90% of the required final volume of tissue culture grade water (e.g., Catalog Number W3500). Example: 900 ml for a final volume of 1000 ml.
      2. While stirring, add the powdered product.
      3. Rinse the original container with a small volume of tissue culture grade water to remove traces of the powder. Add to the solution in step 2.
      4. Add desired supplements (e.g., sucrose, gelling agent, auxins, cytokinins).
      Add heat labile constituents after autoclaving.
      5. While stirring, adjust to the desired pH (e.g., 5.7±0.1) using KOH, NaOH, or HCl.
      6. Add additional tissue culture grade water to bring the medium to the final volume.
      7. If a gelling agent is used, heat the solution to clarity while stirring.
      8. Dispense the medium into culture vessels before or after autoclaving according to the application.
      Add heat labile constituents after autoclaving.
      9. Sterilize the medium in a validated autoclave at 1 kg/cm2 (15 psi). The medium should attain a temperature of 121 °C for at least 15 minutes.

  2. What is the difference between Product M5519, Murashige and Skoog (MS) Basal Medium and M5524, Murashige and Skoog Basal Salt Mixture?

    1 answer

    1. Product M5524 is the Murashige and Skoog(M&S) Basal Salt Mixture, only. The M5519 products is M&S Basal Medium which also includes the vitamins myo-Inositol, Nicotinic acid and Pyridoxine HCl. These formulations are identical with the exception of vitamin components. With the addition of 1 mL of M7150 M&S Vitamin Solution, the composition of each medium is equivalent.

  6. once the media is prepared, what conditions should it be stored in, and how long can it be stored?

    1 answer

    1. The prepared solution is quite stable but should be stored refrigerated. Monitor the salt solution for particulates or turbidity. After the addition of agar and subsequent sterilization, poured plates or vessels should also be stored aseptically in the refrigerator until use. The shelf life of the stored plates or vessels is most often limited by less stable compounds added to the medium. The end user would have to determine the stability of these components. While there is no firm shelf life on the prepared medium, contamination, and drying are the most common reasons for degradation. Monitor plates/vessels for contaminants or turbidity. An indication of excessive drying will be the gelled medium pulling away from the sides of the plate or vessel. The medium has lost moisture and may not be suitable for use. Moisture loss can be minimized by storing prepared plates/vessels in a sealed container or sealed bags. Please see the link below to review the product datasheet:

  7. What is the percentage of sucrose in M5519?

    1 answer

    1. The M5519 does not contain sucrose. This component would have to be added prior to autoclaving. The typical amount is 30 g/L. See the link below to review the product information sheet:
      https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/361/537/m5519pis.pdf

      Should sucrose be desired, see product M9274, which is more of a complete formulation containing M&S salts, vitamins, sucrose, and agar. See the link below to review the formulations of the various Murashige & Skoog media:

  10. Product M5519, Murashige and Skoog Basal Medium, has precipitates; will that affect the growth?

    1 answer

    1. Precipitates are known to occur, with time, in plant tissue culture media.  The precipitates have been analyzed.  They are composed of small pale yellow-white particles.  Analysis of precipitates indicated a predominance of iron, phosphate, and zinc.  The probable cause of the precipitates is the inevitable oxidation of ferrous ions to ferric ions and the presence of unchelated ferric ions.  When the solubility of ferric phosphate is exceeded precipitation occurs.  There are no reports of detrimental effects on growth and development in plant tissue culture due to the precipitates.
