| 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. |

Express System |
HEK293 |
| Purity | > 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC |
| Endotoxin | Less than 1EU per ug by the LAL method. |
| Form | Lyophilized |
| Shipping | Shipped at ambient temperature. |
| Formulation | Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| Reconstitution | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
