General description

Typical working concentration: 1.5-2.5 g/L in plant tissue culture media; up to 10 g/L in microbiological media. Phytagel requires the presence of cations (especially divalent) for gelling to occur. Concentrations of calcium and magnesium contained in most plant tissue culture media are typically sufficient for gelation. Low-salt media formulations, especially those used in microbiological applications, may require supplementation with additional calcium or magnesium salts (e.g., CaCl2 or MgSO4) or higher concentrations of Phytagel.


Phytagel has been used:
  • in the solidification of culture medium for root assays in Arabidopsis thaliana
  • as a component of Solid Paul′s medium for Agrobacterium culture
  • as a component of root induction medium in Ilex dumosa tissue culture


100, 250, 500 g in poly bottle
1, 5 kg in poly drum

Biochem/physiol Actions

Phytagel is intended for use in place of agar and other gelling agent for plant tissue culture. Phytagel has been shown to be a superior substitute for tissue-culture-grade agar in the micropropagation of banana plantlets.

Other Notes

An agar substitute produced from a bacterial fermentation composed of glucuronic acid, rhamnose and glucose. It produces a clear, colorless, high strength gel which aids in detection of microbial contamination.


To prevent clumping, add slowly to rapidly stirring medium prior to heating.

Developmental plasticity is one of the most striking features of plant morphogenesis, as plants are able to vary their shapes in response to environmental cues. Biotic or abiotic stimuli often promote organogenesis events in plants not observed under normal growth...
