Genomic DNA isolation - (May/30/2002 )

I am seeking for the best kit for the small-scale isolation of total DNA from actinomycetes (mainly Streptomyces) for the purpose of restriction analysis, blotting, PCR, cloning. (Need to isolate DNA from numerous strains - environmental samples).


Maybe this helps:
Association of Myosin Immunoanalogue with Cell Envelopes of Aspergillus fumigatus Conidia

7 x 108 were disrupted in 1ml PBS containing protease inhibitors in the MSK with cooling. The glass beads were removed, followed by centrifugation of the homogenate at 5,000 x g for 3 mins.
For these homogenizations the MSK was used with the cooling capillary and a mix of glass beads diam. 1 mm and 0.25 0.3 mm.
