This study has investigated the potential of immersion coating calcium containing pellet cores first with pectin, and then with two different cross-linkers, calcium or chitosan. The interaction between pectin and calcium, and between pectin and chitosan, are believed to slow

Insulin-loaded calcium pectinate nanoparticles were prepared as a potential colonic delivery system by ionotropic gelation with calcium ions. The effects of pectin molecular weight (Mv) and formulation pH on the characteristics of the nanoparticles were evaluated. Commercial pectins, LM101 and

Immunocytochemistry of pectins in shoot apical meristems: consequences for intercellular adhesion
To measure pectinase activity, a titrimetric stop reaction assay is used. One unit of pectinase will liberate 1 μmol of galacturonic acid from poly-galacturonic acid per hour at pH 4.0 at 25 °C.
