Lavofloxacin lactate ((-)-ofloxacin lactate) is a class of broad-spectrum antimicrobials that can kill or inhibit a variety of bacteria. Lavofloxacin lactate binds to DNA rotase and topoisomerase IV, resulting in blocked DNA replication and repair, thus inhibiting bacterial growth. Lavofloxacin lactate can be used to study resistance mechanisms in bacteria, including studying resistance genes and mutations.

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.
