Die schnelle und vollst\u00e4ndige Vernetzung wird durch die langsamer eindringenden Glutaraldehyd-Oligomere verursacht. <strong>Diese Mischung ist mit dem Namen Morris J. Karnovsky<\/strong> aus Boston verbunden. Dies ist ein Beispiel f\u00fcr eine gro\u00dfe Innovation, die nur in einer nicht \u00fcberarbeiteten Zusammenfassung ver\u00f6ffentlicht wurde (Karnovsky, 1965). Die urspr\u00fcngliche Mischung enthielt 4 % Glutaraldehyd, was eine h\u00f6here Konzentration war, als viele Menschen verwenden wollten (Hayat, 1981). Bezeichnungen wie<br \/>\n&#8222;Karnovsky bei halber St\u00e4rke&#8220; wurde in den 1960er und 1970er Jahren zum allgemeinen Sprachgebrauch. Fixierer dieses Typs erm\u00f6glichten definitive Beschreibungen der Histologie auf EM-Ebene, die in den n\u00e4chsten 5 oder 6 Jahren mit der Einf\u00fchrung des Fixierers von Karnovsky erreicht wurden, und sie werden immer noch h\u00e4ufig verwendet.<\/p>\n<p>Die Referenzen<\/p>\n<p>Baker, JR (1958).
