Anti-Pectic polysaccharide (Homogalacturonan) [LM19] Antibody

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


  • Reacts with land plants pectic polysaccharide, homogalacturonan
  • Has no known cross-reactivity with other polymers
  • Binds to unesterified homogalacturonan
  • Suitable for Immunofluorescence and ELISA applications

The antibody recognizes the homogalacturonan domain of pectic polysaccharides. It has no known cross-reactivity with other polymers. It can recognize pectic polysaccharides in several species. The antibody recognizes a range of homogalacturonan samples but appears to have a preference for and binds strongly 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.
