Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 57 kDa.Can be blocked with IL28 Receptor alpha peptide (ab195307). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Relevance
    IL28RA is a class II cytokine receptor that interacts with IL10RB to bind IL28A, IL28B, and IL29, which are related to type I interferons. These ligands play a critical role in response to microbial challenge and activate the JAK/STAT signaling system. It heterodimers with IL10RB. There are 4 isoforms as result of alternative splicing. It is widely expressed. IL28RA belongs to the type II cytokine receptor family, and contains 1 fibronectin type III domain.
