SPR719 (VXc-486) is an orally active gyrase B inhibitor, with bactericidal activity. SPR719 potently inhibits multiple agent-sensitive isolates and drug-resistant isolates of Mycobacterium tuberculosis, with MICs of 0.03 to 0.30 μg/ml and 0.08 to 5.48 μg/ml, respectively. SPR719 is promising for research of lung disease caused by non-tuberculous mycobacteria (NTM).

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.
