This Mouse IL13RA1 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of IL13RA1 protein (Cat: 50088-M08H) from the overexpression lysate was verified.
A DNA sequence encoding the extracellular domain (Met 1-Thr 340) of mouse IL13Rα1 (NP_598751.3) precursor was fused with the a polyhistidine tag at the C-terminus.
The recombinant mouse IL13Rα1 consists of 326 amino acids after removal of the signal peptide and has a predicted molecular mass of 37.6 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm IL13Rα1 is approximately 50-55 kDa due to glycosylation.

Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Interleukin 13 receptor, alpha 1, also known as IL13RA1/IL-13RA1 and CD213A1 (cluster of differentiation 213A1), is a subunit of the interleukin 13 receptor. This subunit forms a receptor complex with IL4 receptor alpha, a subunit shared by IL13 and IL4 receptors. IL13RA1/IL-13RA1 serves as a primary IL13-binding subunit of the IL13 receptor, and may also be a component of IL4 receptors. This protein has been shown to bind tyrosine kinase TYK2 and thus may mediate the signaling processes that lead to the activation of JAK1, STAT3, and STAT6 induced by IL13 and IL4. IL13RA1/IL-13RA1 binds with low affinity to interleukin-13 (IL13). This subunit together with IL4RA can form a functional receptor for IL13. IL13RA1/IL-13RA1 also serves as an alternate accessory protein to the common cytokine receptor gamma chain for interleukin-4 (IL4) signaling, but cannot replace the function of IL2RG in allowing enhanced interleukin-2 (IL2) binding activity.
