Radioactivity of putative protein cores, each (one to three gel bands) expressed as a fraction of the total radioactivity of the PG sample (one gel lane). All observed putative PG core bands were analyzed except for the soluble HSPG band, which was too faint to measure accurately. In a few cases, because their spatial proximity prohibited accurate resolution of the single bands, two to three of the high molecular weight CSPG bands were measured together.
