Beschreibung

Allgemeine Beschreibung

Agar or Agar-agar is one of the major components found in the cell wall of red algae. It is a polysaccharide complex, comprising about 70% agarose and 30% agaropectin.

Anwendung

Washed agar has been used:

• as a supplement (0.9% w/v) to Murashige and Skoog basal medium for plant growth[1]
• in the preparation of cocultivation medium for Agrobacterium tumefaciens mediated transformation in maize (Zea mays) hybrid Hi-II[2]
• as a component in the complete medium to regenerate protoplasts of Piriformospora indica[3]
• as a clean agar medium to culture Synechococcus WH7803 strain[4]

Biochem./physiol. Wirkung

Agar is an ester of sulfuric acid in a linear galactan form, that makes it soluble in hot water and insoluble in cold. Washed agar contain less impurities and low level of nutrients.
