TIB Molbiol results, melt curve. A Positive control, wild type, one peak at 51 °C for wild type position 484, a second peak at 56 °C for wild type position 501. B Naso-pharyngeal swab collected on April 28th: a double peak is observed for position 484: the main first peak at 51 °C (wild type 484) and a second smaller one at 54.6 °C (E484K); the third peak at 61 °C is N501Y. C Bronchoalveolar lavage collected on May 5th where a double peak is again observed: the main peak at 54.3 °C (E484K) and a smaller one at 51.3 °C (wild type 484); the N501Y peak at 61 °C is unchanged.
