ABSTRACT
BACKGROUND:
One of the most challenging aspects of nucleic acid amplification tests is the extraction of genomic DNA. However, achieving satisfactory quality and quantity of genomic DNA is not always easy, while the demand for rapid, low-cost and less laborious DNA isolation methods is ever-increasing. METHODS ANDRESULTS:
We have developed a rapid (â2 min) crude DNA extraction method leading to direct-PCR that requires minimum reagents and laboratory equipment. It was developed by eliminating the time-consuming purification steps of DNA extraction, by processing the sample in optimized amounts of Taq KCl PCR buffer and DNARelease Additive/Proteinase K in only two minutes and carrying out amplification using conventional Taq DNA polymerase. The DNA preparation method was validated on muscle tissue samples from 12 different species as well as 48 cooked meat samples. Its compatibility was also successfully tested with different types of PCR amplification platforms extensively used for genetic analysis, such as simplex PCR, PCR-RFLP (Restriction Fragment Length Polymorphism), multiplex PCR, isothermal amplification, real-time PCR and DNA sequencing.CONCLUSIONS:
The developed protocol provides sufficient amount of crude DNA from muscle tissues of different species for PCR amplifications to identify species-of-origin via different techniques coupled with PCR. The simplicity and robustness of this protocol make nucleic acid amplification assays more accessible and affordable to researchers and authorities for both laboratory and point-of-care tests.Palabras clave
