ABSTRACT
<p><b>OBJECTIVE</b>To establish a convenient, practical and high efficient method of DNA extraction of os cervi, and lay the foundation of identification of animal bones.</p><p><b>METHOD</b>The bones of sika deer, red deer, cattle, dog and pig were used to extract DNA under different decalcification time (24,48,72 h) and decalcification temperature (4,25,37,56,70 degrees C), and extract method.</p><p><b>RESULT</b>It proved by experiments that demineralization process promotes the cracking of osteocyte. In a broad of decalcification time and temperature, DNA could be extracted from all bone samples successfully while the quantity varied slightly.</p><p><b>CONCLUSION</b>Samples (about 0.1 g) decalcify with 0. mol x L(-1) EDTA at 4 degrees C for 24 h, then water-bath for 1 h after lysis buffer added, DNA extracted via the method above is of high quality and can be used for PCR.</p>
