Application Notes
Agar is produced from a family of red seaweeds (Rhodophycae) primarily from two genera, Gelidium and Gracilaria. Agar is a mixture of agarose and agaropectin. Product A175 is produced from Gelidium and typically has higher gel strength than those produced from Gracilaria. 2
Agar is by far the most common gelling agent used in plant tissue culture. It is used at a wide range of concentrations from 6 g/L for a slightly firm gel to 10 g/L for a brick-like gel; however, 6-8 g/L is the more commonly used range.
PhytoTechnology Laboratories® also carries agar produced from Gracilaria, Product No. A111.
Please Note: While PhytoTechnology Laboratories® tests each lot of this product with two or more plant cell/ tissue culture lines, it is the sole responsibility of the purchaser to determine the appropriateness of this product for the specific plants that are being cultured and applications that are being used.
