Technical Support

Bezlotoxumab (BLA761046; MBL-CDB1; MDX-1388) is a fully humanized IgG1/kappa monoclonal antibody directed against Clostridium difficile toxin B. Bezlotoxumab mediates the early reconstitution of gut microbiota to reduce the risk of recurrent Clostridium difficile infection (CDI). Bezlotoxumab can be used for the study of recurrent Clostridium difficile infection prevention.

In Vitro

Bezlotoxumab (100 μg/mL, 18 h pre-treatment) neutralizes TcdB-induced TER reduction in Caco-2 and MOCK cell monolayers[1].
Bezlotoxumab (100 μg/mL, 18 h pre-treatment) shows increased transport to the apical chamber of Caco-2 cells with rising TcdB concentration[1].
Bezlotoxumab (100 μg/mL, 18 h pre-treatment) inhibits TcdB-induced TER decrease in T84 cell monolayers, with Fc-independent neutralizing effects[1].

In Vivo

Bezlotoxumab (250 μg/mouse, i.p., 1 day pre-infection) improves survival of both WT and FcRn-/- C57BL/6 mice in primary CDI model, combined with Actoxumab (HY-P99277)[1].
Bezlotoxumab (50 mg/kg, s.c., q.d. for 4 days) enhances survival and reduces symptoms in 100 g male Syrian hamsters with CDI combined with Actoxumab[1].

Die Formel zur Berechnung von Molaritäten

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

Mass   Concentration   Volume   Molecular Weight *
= × ×

The dilution calculator equation

Konzentration (Stammlösung) × Volumen (Stammlösung) = Konzentration (Ziellösung) × Volumen (Ziellösung)

Diese Gleichung wird häufig abgekürzt als: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

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.
