The existence of 2 kinds of proteoglycans was shown by agarose-polyacrylamide gel electrophoresis; their molecular weights were estimated based on the mobility on agarose-polyacrylamide gel electrophoresis and on K&lt;sub&gt;av&lt;\/sub&gt; values on gel chromatography. One proteoglycan was protein-rich with a molecular weight of 1.15 \u00d7 106, while the other was free from protein or contained a little protein, and had a molecular weight of 4.9 \u00d7 105.<\/jats:p>","DOI":"10.1159\/000265490","type":"journal-article","created":{"date-parts":[[2009,12,7]],"date-time":"2009-12-07T12:10:25Z","timestamp":1260187825000},"page":"170-177","source":"Crossref","is-referenced-by-count":1,"title":["Proteoglycans from Pterygium Tissues"],"prefix":"10.1159","volume":"19","author":[{"given":"Masayuki","family":"Kaneko","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,12,4]]},"container-title":["Ophthalmic Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000265490","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:28:47Z","timestamp":1777706927000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000265490"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,12,4]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[1987,3,1]]},"published-print":{"date-parts":[[1987,3,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000265490","archive":["Portico"],"relation":{},"ISSN":["0030-3747","1423-0259"],"issn-type":[{"value":"0030-3747","type":"print"},{"value":"1423-0259","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,12,4]]}}}
