| Abstract | ||
| DNA isolation is the first step for most molecular tests, thus indicating the importance of using a reliable and suitable method for this procedure. The use of magnetic nanoparticles for blood DNA isolation offers several advantages including subjecting little mechanical stress to your sample, obtaining higher quality and quantity of DNA, and non-laborious procedures. In this study, we isolated genomic DNA using gelatin-coated magnetic nanoparticles from blood samples and test its use compare with three commercial blood DNA isolation kits. DNA purity and yield were assessed by measuring absorbance at A260/A280 and by agarose gel electrophoresis. The suitability of the isolated DNA for downstream applications was analyzed by end-point PCR and Sanger sequencing. In this study, gelatin-coated magnetite particles for genomic DNA isolation provide an efficient, simple, and inexpensive method that does not require the use of commercial blood DNA Isolation Kit. | ||
