Macromolecular architecture and hydrodynamic properties of human cervical mucins
Abstract:
Cervical mucus glycoproteins (mucins) were extracted by using slow stirring in 6M-guanidinium chloride supplemented with proteinase inhibitors. Subsequent purification was achieved by isopycnic density-gradient centrifugation in CsCl/guanidinium chloride. The whole mucins (Mr 10 X 10(6) - 15 X 10(6)) were degraded into subunits (Mr 2 X 10(6) - 3 X 10(6)) by reduction. Trypsin digestion of subunits afforded glycopeptides (T-domains) with Mr 0.4 X 10(6). The relationship between the intrinsic viscosity and Mr for the whole mucins and the fragments suggests that cervical mucins are linear flexible macromolecules. This view is supported by hydrodynamic data.
