The JIM5, rat, monoclonal antibody recognises the α-1,4-linked homogalacturonan domain of pectic polysaccharides. It has no known cross-reactivity with other polymers. It can recognise partially methyl esterified epitopes of pectic polysaccharides (homogalacturonan) in several species and also binds unesterified homogalacturonan.
LM19 is recommended for the detection of unesterified homogalacturonan.
