Comparative study of total DNA isolation methods from different types of biological samples

Duţă-Cornescu G, Stanciu F, Neagoe I, Stoian V. Romanian Biotechnological Letters, 2005;10(1):2011-2018.


Any tic analysis it’s starts with the tic material extraction. On the quality and quantity of the extracted or RNA depends the success of any further research. The development of new molecular techniques have made possible for us to analyse any type of biological sample, from an insect embedded in residues, to fossils and to forensic samples.
In this article the authors are presenting a comparative study of the most used extraction methods and there own experimental modifications, using as starting material a wide range of biological samples. The purpose of this study is to create the best extraction method adapted to the particularities of our samples and our laboratory. These methods will be used to obtain a high quality , suitable for our further experiments
