Supreme TC Grade Agar

Solidifying agents play a vital role in tissue culture media, providing essential support for the optimal growth and development of plants when incorporated into the medium. Additionally, the inclusion of solidifying agents helps ensure the even distribution of nutrients, hormones, and other crucial elements throughout the culture medium.

The two most common solidifying agents used in the process are agar and gellan gum. Agar, derived from seaweed, is a polysaccharide. It imparts a gel-like texture to the medium, facilitating the adherence, growth, and differentiation of plant cells.

The benefits of agar as tissue culture media

• Easy to use
• Acts as a solid support for the growth and development of explants
• Allows the absorption of nutrients by the plant cells
• Cost-effective

How To Use Agar
