High ArthritoMabTM Antibody Cocktail Activity | 18-day RA Model Balb/c Mice

MD Bioproducts, a global biotechnology company focused in inflammations research, has optimized ArthritoMabTM Antibody Cocktail for the induction of arthritis in C57Bl/6. Using the optimized ArthritoMab Antibody Cocktail, investigators can induce arthritis in C57Bl/6 strains with as little as 2 mg of antibody and see good clinical disease scores as well as pannus formation, bone erosion, hyperplasia and cellular infiltration at the histological level. 

The optimized ArthritoMabTM antibody cocktail relies on the same four clones of antibody selected for use in the original cocktail, allowing researchers to continue to obtain comparative data without introducing unknown variables caused by additional antibody clones. The monoclonal antibody clones in the cocktail were selected to bind to C1, J1, U1 and D3 epitopes, which are well documented epitopes associated with arthritis in the collagen-induced arthritis (CIA) model. These epitopes are also spread across the entire CII region (fragments CB8, CB10 and CB11) to encourage better immune complex formation on the cartilage surface for initiation of arthritis.

With the increase in use of transgenic strains such as C57Bl/6 for the study of arthritis, investigators are often faced with low incidence rates in the CIA model. Alternatively, while the Collagen antibody-induced arthritis (CAIA) has been a good alternative for increasing the rates of incidence, often times the amount of antibody required in C57 strains is cost prohibitive. MD Bioproducts has optimized the ArthritoMabTM antibody cocktail enabling investigators to achieve high incidence rates (100%) in C57 strains while controlling costs in the amount of antibody required (as little as 2 mg of Antibody).

For years, the CIA model has been the standard for arthritis studies. Issues such as length of model, staggered disease onset, low disease induction, lab to lab variations, number of administration timepoints and clinical scoring periods caused researchers to look for a viable alternative. The collagen antibody induced arthritis model (AIA or CAIA) using ArthritoMabTM Antibody Cocktail is a reliable alternative providing results in just 12 days, high rates of incidence and synchronized disease onset.
