Species | Human |
Tag | C-His |
Expression Systems | Expi293 |
Keywords | Human; C-His; Expi293 |
Synonyms | CD357; GITR; GITR-D; TNFRSF18; AITR |
Background | GITR (glucocorticoid-induced tumor necrosis factor receptor), also known as AITR and TNFRSF18, is a 40 kDa transmembrane glycoprotein that functions in immune regulation. GIRT is a receptor for TNFSF18. Seems to be involved in interactions between activated T-lymphocytes and endothelial cells and in the regulation of T-cell receptor-mediated cell death. Mediated NF-kappa-B activation via the TRAF2/NIK pathway. |
Source | Recombinant Human GITR/TNFRSF18 Protein is expressed from Expi293 with His tag at the C-terminal. It contains Gln26-Glu161. |
Molecular Weight | The protein has a predicted MW of 15.4 kDa. Due to glycosylation, the protein migrates to 25-28 kDa based on Tris-Bis PAGE result. |
Endotoxin | Less than 1 EU per μg by the LAL method. |
Purity | >95% as determined by Tris-Bis PAGE. >95% as determined by HPLC. |
Formulation | Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution | Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage | -20 to -80℃ for 12 months as supplied from the date of receipt. -20 to -80℃ for 3-6 months in an unopened state after reconstitution. 2-8℃ for 2-7 days after reconstitution. |
Notes | Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. |
