产品描述 概述Recombinant Human 4-1BB Ligand Receptor is produced by our Mammalian expression system and the target gene encoding Leu24-Gln186 is expressed with a 6His tag at the C-terminus. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. 技术规格| Tag | C-6His | | 种属 | Human | | 表达系统 | Human cells | | Accession# | Q07011 | | Source | Human Cells | | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. | | Storage | Lyophilized protein should be stored at < -20°C, thoμgh stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. | | Reconstitution | Dissolve the lyophilized protein in distilled water. | | Purity | Greater than 95% as determined by reducing SDS-PAGE. | | Endotoxin | Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test. | | Background | Tumor necrosis factor receptor superfamily member 9(TNFRSF9), also known as CD137 and 4-1BB, is an inducible T cell surface protein belonging to the tumor necrosis factor receptor superfamily. It is a single-pass type I membrane protein which contains 4 TNFR-Cys repeats. The human and mouse proteins share 60% amino acid sequence identity. CD137 is expressed by mesenchymal cells, including endothelial cells, chondrocytes, and cells of the central nervous system. CD137 is also broadly expressed by cells of the human immune system, is broadly expressed by cells of the human immune system, including activated CD8+ and CD4+ T cells, activated natural killer (NK) cells, follicular dendritic cells (FDCs) and monocytes. CD137 has diverse roles in the immune response, the one key function is to promote the survival of both T cells and dendritic cells by binding the cognate ligand CD137L (4-1BBL). | | Biological_Activity | Measured by its ability to bind Human TNFSF9 in functional ELISA. The ED50 for this effect is 1-5 μg/ml. |
