Detection and haplotype differentiation of Southeast Asian α-thalassemia using polymerase chain reaction and a piezoelectric biosensor immobilized with a single oligonucleotide probe
DNA-based diagnosis of α-thalassemias routinely relies on polymerase chain reaction (PCR) and gel electrophoresis. Here, we developed a new procedure for the detection and haplotype differentiation of Southeast Asian (SEA) α-thalassemia using a 3-primer system for PCR coupling with a DNA-based piezo...
