Anti-Pectic polysaccharide (Homogalacturonan) [LM7] Antibody

This rat IgM monoclonal antibody was generated against polysaccharide and recognizes land plants pectic polysaccharide, homogalacturonan.


  • Reacts with land plants pectic polysaccharide, homogalacturonan
  • Binds to paritally methyl esterified homogalacturonan
  • Does not bind to un-esterified homogalacturonan
  • Suitable for Immunofluorescence and ELISA applications

The antibody recognizes the homogalacturonan domain of pectic polysaccharides. It can recognize pectic polysaccharides in several species. The antibody recognizes a partially methyl-esterified epitope of HG that results from non-blockwise de-esterification processes. It does not bind to un-esterified homogalacturonan. Homogalacturonan is a pectic polysaccharide made up of α-1,4 linked galacturonic acid residues. Pectin is made up of a complex set of polysaccharides that are found in most primary cell walls and are particularly abundant in the non-woody parts of terrestrial plants. Pectin is a major component of the middle lamella, where it helps to bind cells together, but is also found in primary cell walls.
