Validation of a quick and low-cost DNA extraction protocol applicable to long-stored blood samples

- Our protocol showed good results in the quantitative and qualitative evaluations.
- DNA extracted by the adapted protocol obtained the best purity parameters.
- DNA extracted by our protocol proved to be well conserved and suitable for use in WGS.
- Cost per sample was much lower than that of similar commercial methods.
- Our protocol is an alternative with easy implementation in the laboratory routine.
