Tumor necrosis factor receptor superfamily member 9 (TNFRSF9), partial (Active), human, recombinant

Organism: Homo sapiens (Human). Source: Mammalian cell. Expression Region: 24-186aa. Protein Length: Extracellular Domain. Tag Info: C-terminal 6xHis-Fc-tagged. Target Protein Sequence: LQDPCSNCPA GTFCDNNRNQ ICSPCPPNSF SSAGGQRTCD ICRQCKGVFR TRKECSSTSN AECDCTPGFH CLGAGCSMCE QDCKQGQELT KKGCKDCCFG TFNDQKRGIC RPWTNCSLDG KSVLVNGTKE RDVVCGPSPA DLSPGASSVT PPAPAREPGH SPQ. Purity: Greater than 95% as determined by SDS-PAGE. Endotoxin: Less than 1.0 EU/µg as determined by LAL method. Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized Human 4-1BB-Fc-His at 2µg/ml can bind Anti-Human CD137 mAb, the ED50 of Anti-Human CD137 mAb is 0.41ug/ml. Form: Lyophilized powder. Buffer: Lyophilized from a 0.2 µm filtered 1xPBS, pH 7.4. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Tumor necrosis factor receptor superfamily member 9(TNFRSF9) is an inducible T cell surface protein belonging to the TNF 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. It is absent from naive T cells, but upregulated and continually expressed following T cell activation. It is a receptor for TNFSF9/4-1BBL, and possibly active during T cell activation. Reference: n/a. Function: Receptor for TNFSF9/4-1BBL. Possibly active during T cell activation.
