General description
Gelrite, gellan gum, is recommended as a gelling agent for use in place of agar in microbiological assay and tissue culture media. Gellan gum is used in a wide variety of immobilization matrices. It forms a hard gel at low concentrations in the presence of an electrolyte. Gellan is a linear tetrasaccharide composed of D-glucose, L-rhamnose, and D-glucuronic acid in the ratio of 2:1:1, linked by β (1 → 4) glycosidic bond.
Application
Gelrite, gellan gum, is recommended as a gelling agent for use in place of agar in microbiological media. Gellan gum is used in a wide variety of immobilization matricies.
