Molecular characteristics of some commercial high‐molecular‐weight hyaluronans

Abstract
Commercially available hyaluronan (HA) samples were investigated by the method of size exclusion chromatography (SEC). The fractions eluted from the SEC column were on‐line molecularly characterized by using a multi‐angle laser light scattering (MALLS) photometer. Along with the SEC‐MALLS technique, the high‐molecular‐weight HA biopolymers were (off‐line) analyzed by capillary viscometry. Copyright © 2002 John Wiley & Sons, Ltd.
