Anti-IgE [R1E4] Antibody

This rat IgG1 monoclonal antibody was generated against immunoglobulin E (IgE) in adjuvant and recognizes mouse Fc of IgE.


  • Reacts with mouse IgE (epitope: Fc)
  • Blocks IgE binding to mouse or rat FceRI
  • Suitable for ELISA applications

Immunoglobulin E is an antibody only found in mammals and its main function is immunity against parasites. IgE also has an essential role in type I hypersensitivity, such as allergic asthma, sinusitis, allergic rhinitis, food allergies, and specific types of chronic urticaria and atopic dermatitis.
