Product Description | Recombinant Biotinylated Human IL-13Ra1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Ala27-Thr343. |
Product Background |
Two type 1 membrane proteins belonging to the hemopoietin receptor family have been cloned and shown to bind IL-13 with differing affinities. The lower affinity IL-13 binding protein, previously designated IL-13 R alpha, IL-13 R alpha ' or NR4, is now referred to as IL-13 R alpha 1. The high-affinity IL-13 binding protein, previously also designated IL-13 R or IL-13 R alpha ', is now referred to as IL-13 R alpha 2. |
