Plant Culture Media Gellan Gum

Plant Culture Media Gellan Gum is a hydrocolloid used in plant tissue culture and botanical research. It serves as a gelling agent in the media that supports plant growth in vitro, offering a clear, stable, and nutrient-rich environment. This product is known for its superior transparency and stability compared to traditional gelling agents like agar, making it highly effective for precise and efficient plant cultivation in laboratory settings. It is particularly valued for its consistency, cost-efficiency, and natural derivation, typically from corn.

Agar Agar Powder is for PTC Plant Growing Gels medium for a long time, but as a more transparent and stable gelling agent, LAT Type Gellan Gum (also know as Gelrite or Phytagel ) has replaced Agar Agar for vitro plants productions.

The appearance of LAT gellan gum is white floating fine powder. LAT Gellan Gum is for Plant Growing Gels, as well as Cell Tissue Culture Media. It could be used as perfect replacement of Agar Agar , or combined with agar is also a good solution for Tissue Culture Media application.

The transparency of LAT Type Gellan Gum Gels and Solution could be 90% and is much better than Agar Products.

The Gel. Strength of LAT Type Gellan Gum could be 400g/cm2 – 1300g/cm2 subject to different application conditions.

Typical Dosage: Regular recommended dosage is 0.015%-0.4% subject to different application.

Features of Gellan Gum LAT:

1. Wide pH application condition ;
2. Heat Irreversible Gels;
3. Clear Gels with extremely high transparency 90% ;
4. Derived from Corn; Natural and large supplying quantity;
5. 1/4 Dosage compared with Agar, cost efficiency;

LAT Gellan Gum Use Step:

► Use at 2-4 g/L for best results
► Produces a clear and firm gel upon autoclaving at 121° C (250° F)
► LAT Gellan Gum is compatible with a wide variety of media and is stable over a wide pH range.

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.
