The outgrowth of M. smegmatis bd-KO in presence of Q203 is not due to selection of mutant harboring compensatory mutations. After eventual growth resumption in presence of Q203 (Telacebec) at ~40 h (green curve), the bacteria were re-treated with Q203 (Telacebec) by diluting into fresh 7H9 complete medium containing the drug (blue curve) or re-grown in drug-free 7H9 complete medium for 16 h, and subsequently again diluted into fresh 7H9 complete medium containing the drug.

Colony forming units (CFU/mL) were subsequently counted on agar plates after three days of incubation at 37 °C. Data are Mean ± SD from two independent experiments (biological replicates), each comprising three technical replicates.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
