| Source name |
genomic DNA from ectocarpus
|
| Organism |
Ectocarpus siliculosus |

| Extraction protocol |
Genomic DNA was extracted from cells of ectocarpus. The DNA extraction protocol described by Apt et al.^2 was optimised for the Ec 32 strain. About one gram of tissue was ground to a powder under liquid nitrogen in a mortar and pestle using sand. After addition of 2 ml of extraction buffer (100 mM Tris-HCl pH 7.5, 1.5 M NaCl, 2% CTAB, 50 mM EDTA pH 4.5, 50 mM DTT) the tissue was extracted further in a Wheaton glass grinding tube. Extraction buffer was then added to 15 ml final volume, the sample shaken vigorously for 10 min and then incubated at 55°C for 2 hours in the presence of 25 units of proteinase K. After extraction with 1 volume of chloroform:isoamyl alcohol (24:1), polysaccharides were precipitated with 0.3 volumes of 100% ethanol and the chloroform-isoamyl alcohol extraction repeated. RNA was then removed by incubation overnight at 20°C in 4M LiCl and 1% beta-mercaptoethanol and centrifugation at 13,000 rpm for 30 min. The DNA was then precipitated from the supernatant by addition of 0.8 volumes of isopropanol, redissolved in 500 µl of Tris EDTA buffer, extracted with phenol:chloroform:isoamyl alcohol (25:24:1) and then with chloroform:isoamyl alcohol (24:1) and precipitated in 0.3 M sodium acetate and 71% ethanol. The DNA was then purified on a CsCl gradient.
