Biotinylated Human IL-13Ra1 Protein, His-Avi Tag

Description :
FAQ COA 已发表文献 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. Human and mouseIL-13R alpha 1 share 76%aa sequence identity. The extracellular domain of IL-13R alpha 1 is also closely related to that of IL-13R alpha 2. 产品性质 Synonyms IL-13 R alpha 1; IL13R; IL13RA; CT19; IL13RA1; NR4; CD213A1; AI882074 Uniprot No. P78552-1 Source Recombinant Biotinylated Human IL-13Ra1 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Ala27-Thr343. Molecular Weight The protein has a predicted MW of 39.5 kDa. Due to glycosylation, the protein migrates to 55-75 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE and HPLC Endotoxin 1.0EU per 1g of the protein by the LAL method. Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100g/mLis recommended. Dissolve the lyophilized protein in distilled water.
