Additional information Contains 0.05% Sodium Azide

The antibody recognizes a partially methyl-estrified epitope of HG which results from non-blockwise de-estrification processes.
The antibody does not bind to un-estrified homogalacuronan.

The plant cell wall surrounds the plant cell as a complex network of polysaccharides classed as: cellulose, hemicelluloses and pectic polysaccharides and glycoproteins.  Anchored to or embedded into plant cell wall are other polymers, like: lignin, suberin or cutin.  

Homogalacturonan is a pectic polysaccharide of alpha-1,4 linked galacturonic acid residues. Pectin contains a complex set of polysaccharides that can be found in many primary cell walls
