A demineralization protocol pulls mitochondrial cytochrome b from rotten cetacean bone
Nine environmentally degraded cetacean bones yield 7.3-57.1 ng/uL DNA after EDTA/N-lauroylsarcosine/proteinase K demineralization and silica cleanup. Mitochondrial cytochrome b PCR works in all; five sequences call Balaenoptera physalus. The organelle genome is the ID tool.
