DNA Isolation: A Method for Improving the Efficiency of DNA Extraction From Clotted Blood Samples

Abstract

In generally, the genome research of high DNA extraction from clotted blood produced a low quality. The aim of this study is to develop a simple and safe technique to dispering the blood clots by the ball bearing metal shots. The yield and purity of DNA obtained by three steps were significantly different (P < 0.0001), with a higher yield in the modified salting-out method. The salting-out method is simple, efficient and economical for DNA isolation from old clotted blood samples.
