The 1C1 monoclonal antibody reacts with the human CD131 molecule, also known as the common beta subunit (betaC). The common beta subunit associates with the specific alpha subunits of IL-3 receptor, IL-5 receptor and GM-CSF receptor to form high affinity receptors for these cytokines. These cytokine receptors are expressed by neutrophils, eosinophils, monocytes, endothelial cells, fibroblasts and hematopoietic progenitor cells and play a crucial role in growth/activation of eosinophils and in the inflammatory response.
