General description
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.
Application
Washed agar has been used:
- as a supplement (0.9% w/v) to Murashige and Skoog basal medium for plant growth
- in the preparation of cocultivation medium for Agrobacterium tumefaciens mediated transformation in maize (Zea mays) hybrid Hi-II
- as a component in the complete medium to regenerate protoplasts of Piriformospora indica
- as a clean agar medium to culture Synechococcus WH7803 strain
Biochem/physiol Actions
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.
