Tosufloxacin (A-61827) is an orally active fluoroquinolone antibiotic. Tosufloxacin shows a broad spectrum of antibacterial activity against gram-positive and gram-negative bacteria.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Tosufloxacin tosylate hydrate) usually boasts enhanced water solubility and stability.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
