Determination of Polydispersity of a Human Colonic Mucus Glycoprotein Using Rate-Zonal Centrifugation and Laser Light-Scattering
Polydispersity colonic mucins rate-zonal centrifugation light-scattering
2009/6/25
The colonic epithelium is coated by a visco-elastic gel, mucus that lubricates and protects the mucosa from the external environment. Mucus glycoproteins (mucins, MUCs) are major macromolecular compon...
