Abstract
The present invention provides a facile method for separation (fractionation) of HA in a sample over a broad M range, including low M HA, by ion exchange (IEX) chromatography. The present invention also provides an assay method for quantifying in a sample the presence of low M HA in total HA isolated from a biological source. The method involves HA fractionation according to M by use of IEX separation, followed by HA-specific assay of HA size range fractions.
