MD Bioproducts/ArthritoMab™ Antibody Cocktail for inducing Arthritis/50 mg/CIA-MAB-50

Overview
Overview:

The Collagen Antibody Induced Arthritis (CAIA) model is a relevant model for studying the efferent phase of RA, where leukocytes are attracted and respond to the immune complex in the joint. It is induced using a cocktail of antibodies to anti-CII and contains pathogenic features similar to that of RA such as pannus formation, cellular infiltration, synovitis and cartilage/bone destruction.

Benefits of the CAIA model

  • Length of study: Arthritis develops in mice typically within 24-48 hr allowing the completion of a study within 2 weeks reducing the number of assessments and scoring periods.
  • Reduced group size: Rate of incidence is nearly 100% depending on the strain allowing for smaller group sizes.
  • Synchronization: onset of disease is synchronized between animals simplifying treatment schedules.
  • Steady & Controlled disease progression: No rapid & severe disease spikes enabling evaluation of all treatment schedules
  • Susceptibility: Arthritis is induced not only in CIA-susceptible DBA/1 and B10.RIII mice, but also in some CIA-resistant mice, such as Balb/c.
  • Eliminates expensive colonies: Models such as the K/BxN serum transfer model require labs to maintain expensive colonies and the sera can vary from batch to batch.

Figure: Balb/c were administered 2 mg of ArthritoMab antibody cocktail on day 0 followed by a LPS boost on day 3.Unlike competitor products, disease progression is steady and controlled for easy evaluation of prophylactic and therapeutic regimes.
