Active Recombinant Human TNFSF9 Protein (Arg71-Glu254), C-His tagged, Animal-free, Carrier-free

• Cat.No.: TNFSF9-307H
• Product Overview: Recombinant Human TNFSF9 Protein (Arg71-Glu254) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Arg71-Glu254
• Description: 4-1BB ligand (4-1BBL) is a type II transmembrane protein that is part of the tumor necrosis factor (TNF) ligand family. As an inducible co-stimulatory molecule, it presents on several antigen presenting cell (APC) types, including B cells, macrophages and DCs. The interactions between 4-1BB and 4-1BBL trigger pleiotropic effects on the immune response including antigen presenting process, proliferation of CD4 and CD8 positive T-cells, as well as cytokine secretion from T-cells through NFκB, c-Jun, and p38 downstream signal pathways activation. Therefore, 4-1BB and 4-1BBL are recently used for the immunotherapy of cancer.
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce IL-8 secretion in human PBMCs. The ED50 for this effect is 1-5 ng/mL.
• Molecular Mass: The protein has a calculated MW of 20.4 kDa.
  The protein migrates as 20 kDa under reducing condition (SDS-PAGE analysis).
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >95% as determined by SDS-PAGE analysis.
• Storage: This product is stable after storage at:
  -20 centigrade for 12 months in lyophilized state from date of receipt.
  -20 or -80 centigrade for 1 month under sterile conditions after reconstitution.
  Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
• Shipping: The product is shipped with polar packs. Upon receipt, store it immediately at -20 centigrade or lower for long term storage.
