Monoclonal Antibodies against Pectin: Recognition of a Conformation Induced by Calcium

Plant Physiol. 1989 Dec;91(4):1419-24. doi: 10.1104/pp.91.4.1419.

Abstract

Monoclonal antibodies have been produced that recognize a conformation of homopolygalacturonic acid (pectic acid) induced by an optimum concentration of calcium and sodium of about 1 and 150 millinormal, respectively. The epitope recognized is probably part of the dimers of pectin chains associated according to the ;egg box' model.
