Objectives This study aims to develop a simple polymerase chain reaction (PCR) sequence-specific primer method, which will be used to genotype HLA-B*15:02, HLA-B*15:13, and HLA-B*15:21. Methods DNA was extracted from whole blood using a commercial DNA extraction kit. New specific primers were designed. The PCR was optimized for reproducibility and specificity. Parameters investigated included concentrations of MgCl2, primers concentration, and annealing temperature, to produce specific bands of interest. Known DNA samples were selected at random and tested using the PCR method. Results Simultaneously six duplex PCRs were successfully optimized using 1.0 mM MgCl2 and an annealing temperature of 62 °C. The method was also reproducible and specific. The results from the method showed 100% concordance with known DNA samples. Conclusions This study has successfully developed a simple and specific method to simultaneously genotype HLA-B*15:02, HLA-B*15:13, and HLA-B*15:21 using in-house developed PCR-SSP. |
