Outline of Final Research Achievements

We uncovered a ligation-independent pathway of MLPA (Multiplex ligation-dependent probe amplification) and developed a ligation-independent probe amplification system, which can be used to obtain amplified products without both the hybridization and ligation processes. Fragment analysis revealed that the ligation-independent pathway is functional and that ligation is not responsible for the specificity of MLPA. These findings indicate that the feasibility and specificity of MLPA do not rely on ligation. Furthermore, we developed a new assay for rapid identification of quinolone antibiotic resistant Streptococcus pneumoniae by using a ligation-independent probe amplification system.
