Highly purified human cervical mucins were prepared by isopycnic density-gradient centrifugation (Carlstedt et al., 1981). The macro-molecules elute in the void volume of a Sepharose CL 2B column and five sepgrate preparations gave molecular weights between 4.8 and 6.5 × 106 by light-scattering in 6M guanidine hydrochloride (GuHCl). To study the size heterogeneity and polydispersity, sedimentation-velocity experiments were carried out in the analytical ultracentrifuge. In the course of this work new observations were made on the sedimentation behaviour of large mucin molecules.
