Tech Info / Data

Tested Applications:

  • Neutralization

Suggested Applications*:

  • Immunoprecipitation (1-5 μg/ml)
  • Immunohistochemistry (1 μg/ml)

*Please note that these applications are presented for suggested use only and have not been fully evaluated by PBL.



The Type I interferon receptor is a heterodimer consisting of IFNAR1 and IFNAR2. The IFNAR2 subunit provides most of the binding affinity for IFN and IFNAR1 is required for optimum signaling.
