OriGene has developed single B cell cloning technology for recombinant rabbit monoclonal antibody generation. TrueRAB® monoclonal antibodies are a collection of recombinant rabbit monoclonal antibodies developed in house. Scientific studies have shown that rabbit exhibits several different features in its B cell development process that could be good for making antibodies with high affinity and against targets with low immunogenicity in mouse system. Currently OriGene is utilizing this proprietary technology to develop perfect antibodies for immunohistochemistry application and also offering custom project services.


  • Higher affinity and specificity comparing to mouse monoclonal antibodies
  • Low background signal
  • Provides diverse epitope recognition
  • Ideal for the development of antibodies against tough targets
  • Ideal for mouse model study
  • Ideal for demanding applications like IHC on FFPE tissue
