Abstract
We have developed a simple, labor-saving, inexpensive, and rapid single nucleotide polymorphism (SNP) genoty** method that works directly on whole human blood. This single-tube genoty** method was used to successfully and reliably genotype ADH1B and ALDH2 polymorphisms without DNA isolation using a 1.2-mm disc of dried blood and the KOD FX PCR enzyme kit. SNP genoty** was performed by a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. In addition to the labor and expense advantages, the possibility of sample contamination was considerably decreased, since the DNA extraction step was eliminated. In the post-genome era, a simple and inexpensive method for diagnostic analysis is in high demand, and this method will be very useful for genetic diagnoses in biological and medical laboratories.
