ABSTRACT
The emergence of novel variants of concern of SARS-CoV-2 demands a fast and reliable detection of such variants in local populations. Here we present a cost-efficient and fast workflow combining a pre-screening of SARS-CoV-2 positive samples using RT-PCR melting curve analysis with multiplexed IP-RP-HPLC-based single nucleotide primer extensions (SIRPH). The entire workflow from positive SARS-CoV-2 testing to base-specific identification of variants requires about 24 h. We applied the sensitive method to monitor the local VOC outbreaks in a few hundred positive samples collected in a confined region of Germany.
