生物活性

Actoxumab (Anti-C. difficile Toxin A Recombinant Antibody) is a antitoxin antibody against C. difficile toxin A by neutralizing TcdA. Actoxumab prevents both the damage to the gut wall and the inflammatory response, which are associated with C. difficile. Actoxumab has synergy effect with Bezlotoxumab (HY-P9929) targeting TcdB[1].

体外研究
(In Vitro)

Actoxumab (10 mg/kg WT or N297Q mutant (N297Q) actoxumab-bezlotoxumab; 2 h plus 24 h) significantly inhibits cell rounding activity in Vero cells under 2 ng/mL TcdA treatment[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Actoxumab (0.1-10 mg/kg or 50 mg/kg; i.p.; single dose) shows protective effect in multiple murine models of clostridium difficile infection (CDI), including systemic and local (gut) toxin challenge models, as well as primary and recurrent models of infection in mice[1].
Actoxumab shows a synergy with Bezlotoxumab, and (combination dosage of 3, 30, 300 μg/mouse; i.p.; single dose) prevents both epithelial damage and inflammatory disease[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Murine C. difficile infection model in CD1 and C57BL/6 mice (6-8 weeks old)[1]
Dosage: Combination dosage of 3, 30, 300 μg/mouse; or ~0.1, 1, and 10 mg/kg
Administration: Intraperitoneal injection; single dose; 1 hour before 25 ng TcdA or 25 ng TcdB challenge
Result: Protected with Bezlotoxumab, against systemic and intestinal toxin challenge in mice.
Animal Model: Ileal loop model in CD1 and C57BL/6 mice (6-8 weeks old)[1]
Dosage: 50 mg/kg; or combined with 50 mg/kg Bezlotoxumab
Administration: Intraperitoneal injection; single dose
Result: Significantly reduced fluid accumulation in toxin-challenged mice (109.4 mg/cm).

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.
