Product name:Gellan gum
CAS:*********1
Product Description:Gellan gum is a water-soluble polysaccharide
produced by Pseudomonas elodea, a bacterium.Gellan gum, also
branded by few suppliers as Nanogel-TC, Grovgel, AppliedGel,
Phytagel or Gelrite, is used primarily as a gelling agent,
alternative to agar, in microbiological culture. It is able to
withstand **0 °C heat, making it especially useful in culturing
thermophilic organisms. One needs only approximately half the
amount of gellan gum as agar to reach an equivalent gel strength,
though the exact texture and quality depends on the concentration
of divalent cations present. Gellan gum is used as gelling agent in
plant cell culture on Petri dishes, as it provides a very clear
gel, facilitating light microscopical analyses of the cells and
tissues. Although advertised as being inert, experiments with the
moss Physcomitrella patens have shown that choice of the gelling
agent - agar or Gelrite - does influence phytohormone sensitivity
of the plant cell culture.
