Anti-Pectic polysaccharide (Homogalacturonan) [JIM7] Antibody

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


  • Reacts with land plants pectic polysaccharide, homogalacturonan
  • No known cross-reactivity with other polymers
  • Binds to methyl esterified homogalacturonan
  • Does not bind to un-esterified homogalacturonan
  • Suitable for Immunofluorescence and ELISA applications

The antibody recognizes homogalacturonan polysaccharides and has no known cross-reactivity with other polymers. The antibody recognizes partially methyl-esterified epitopes of homogalacturonan but does not bind to un-esterified homogalacturonan. JIM7 can be a good general probe for pectic 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.
