ImmunoPrecise is excited to offer custom Rabbit Monoclonal Antibody development services. Our proprietary technology screens the immune repertoire of the rabbit creating the power to select the desired antibody directly from B-cells.

The Rabbit Advantage

  • Uses proprietary B-cell Select Platform
  • High affinity antibodies without the traditional cell fusion step; avoids stability issues commonly associated with hybridomas
  • Recombinant antibody ensures preservation of genetic information
  • Both a monoclonal and polyclonal end product
  • Utilization of rabbit immune system to generate antibodies against different epitopes on the same antigen
