STUDY ON PREPARATION OF LOW GELLING POINT AGAROSE

In the application of agarose, especially to the research of modern biologic al technology, low gelling point agarose is necessary. Using water fraction of G elidium amansii as raw material, investingations into the preparation of low gel ling point agarose by methylation reaction was carried out. A modified agarose c ontaining alkylated agarose to the standard of low gelling point agarose. Its ma in properties of gel strength(264 g/cm2 1.0% gel), gelling point (30.1 ℃ 1. 5%gel) and melting point (64.8 ℃ 1.5%gel) are all similiar to those produced by Sigma company.
