Abstract:
BACKGROUND:Blood clots can be used to extract DNA, but they are not as widely used as whole blood or buffy coats. This is due not only because of the relatively low DNA yields and quality obtained from blood clots, but also because sampling prior to DNA extraction is more difficult. METHODS:To solve these problems, we compared several clot liquefaction methods, determined the four most feasible methods, and subsequently performed a comparative analysis among them. We compared the yields and optical density ratios of the resulting DNA samples and assessed their integrity using agarose gel electrophoresis, polymerase chain reaction, and next-generation sequencing (NGS). RESULTS:Each of the four methods has advantages and disadvantages. But in general, higher yields of DNA with better quality and integrity were obtained using the high-shear homogenization method than using the other three methods. Additionally, this method is cost-effective and feasible at large operational scales. The DNA yields and A260/280 ratios were optimal and stable, the operation time and labor costs were acceptable, and the success rate of NGS applications was 99.74%. Furthermore, we developed a simple and rapid method for cleaning the homogenizer head to remove residual samples. According to our experimental results, our cleaning method effectively eliminated the risk of cross-contamination caused by the homogenizer head. CONCLUSION:We recommend high-shear homogenization as a superior method for clot liquefaction. We believe that this method is worthy of large-scale application as it can improve the efficiency of DNA extraction from clots, thus reducing labor and economic costs.
