Abstract

A method for the isolation of nuclei from the lower eukaryote, Euglena gracilis, utilizing MES buffer at pH 5.5 and sodium meta bisulfite is presented. The method takes advantage of the finding that sodium meta bisulfite reversibly alters the density of the nuclei allowing them to be separated from cytoplasmic fragments and unbroken whole cells. Nuclei are obtained in a yield of 25-37 %, appear intact ultrastructurally, and contain acid-soluble proteins in an amount relatively the same as found in higher cell nuclei.
