Abstract

Background and objectives: The present study describes the successful adaptation of an in-house Polymerase Chain Reaction (PCR) for Helicobacter pylori detection coupled with the main mutations associated with resistance to clarithromycin in ready-to-use PCR microwell strips.

Materials and methods: These microwell strips can be used on LightCycler® 480, and are delivered with nine microliters of the reaction mixture dispensed into 8-well microwell strips. An extraction control PCR targeting the β-globin household gene is amplified in the same run as H pylori detection.

Results and conclusion: These microwell strips can be stored at -20°C for 1 year and left at room temperature and in the light for up to 4 h with no impact on the PCR results. Microwell strips can also undergo a thaw and refreeze cycle without impacting the PCR results. These PCR microwell strips are available for purchase from Eurogentec.

Keywords: H pylori; PCR; clarithromycin resistance; microwell strip.
