Description

Dalfopristin is a semi-synthetic streptogramin antibiotic. Quinupristin/Dalfopristin (Q/D) is a valuable alternative antibiotic to vancomycin for the treatment of multi-agent resistant Enterococcus faecium infections.

IC50 & Target

Antibacterial[1]

In Vitro

Quinupristin/Dalfopristin(Q/D) is a combination of streptogramins B (Quinupristin) and streptogramins A (Dalfopristin) at 30:70 ratio[1]. Quinupristin/Dalfopristin, a semisynthetic injectable streptogramin, is a combination of 2 synergistic antibiotic components that are derived from pristinamycin: a type B streptogramin (Quinupristin) and a type A streptogramin (Dalfopristin), in a 30:70 weight-to-weight ratio[2].

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.
