摘要：

Swelling and its related changes in agarose gels were investigated. The behavior of agarose gel was different to that of synthetic polymer gels: the agarose gel did not show any swelling or shrinkage in water. The gel shrank only a little in acetone and in ether. The shrunken gel did not recover its original volume again with re-treatment in water. It was found that agarose solution showed a retrogradation-like reaction similar to amylose solution. These anomalous phenomenaincluding syneresis were interpreted based upon the liquid phase separation mechanism for the agarose gelation proposed by us.
