产品说明

一般描述

Agar is a polysaccharide complex obtained through bleaching and hot water extraction of agarocytes from the red alga Rhodophyceae, found in the Pacific and Indian Oceans and the sea of Japan. The genera Gelidium, Acanthopeltis, Ceramium, Pterocladia and Gracilaria predominate in agar production. Agar is composed of about 70% agarose and 30% agaropectin.
Agar is a natural polymer extracted from red alga Rhodophyceae, primarily, consisting of alternative D- and L-galactose units. This type of high gel strength agar is used when a firmer gel is required and mostly suitable for plant cell culture.

应用

Agar has been used:

  • in the preparation of laboratory diet to maintain the culture of D. melanogaster wild-type larva
  • as a high gel strength agar in the seed culture media to grow Arabidopsis thaliana mutant seeds
  • to construct a tissue-mimicking phantom to test the imaging performance of an ultrasound transducer

Agar has been used:
  • as a component of the fruit fly diet
  • as a component of saline-agar for the approximation of gray matter from brain
  • in in vitro root nodulation assay of Glycine max seeds
