Novus' biologically active proteins are stringently purified to provide only the safest and most highly effective proteins available. This protein was expressed in E. coli, purified by HPLC, QC tested by SDS-PAGE and Western Blot and validated on appropriate cell lines for bioactivity. All HPLC and bioactivity data is provided for your assurance.
|Details of Functionality
TNFSF9 protein is fully biologically active when compared to standard. The ED50 as determined by stimulation of IL8 production using human PBMC is less than 10 ng/ml, corresponding to a specific activity of > 1.0 x 105 IU/mg.
Size Exclusion Chromatography
Less than 1 EU/ug of endotoxin as determined by LAL method.
Packaging, Storage & Formulations
Store at 4C short term. Aliquot and store at -20C long term. Avoid freeze-thaw cycles.
Size Exclusion Chromatography
Reconstitute with sterilized distilled water or 0.1% BSA aqueous buffer to a final concentration of 0.1 - 1.0 mg/ml.
This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.
Alternate Names for Human 4-1BB Ligand/TNFSF9 Protein
- 41BB Ligand
- 4-1BB ligand
- homolog of mouse 4-1BB-L
- receptor 4-1BB ligand
- tumor necrosis factor (ligand) superfamily, member 9
- tumor necrosis factor ligand superfamily member 9
41BBL is a member of the tumor necrosis factor (TNF) receptor family. This receptor contributes to the clonal expansion, survival, and development of T cells. In addition, 41BBL expression is found on dendritic cells, follicular dendritic cells, natural killer cells, granulocytes and cells of blood vessel walls at sites of inflammation. CD137 has been shown to interact with TRAF2. The human 41BBL gene codes for a 254 amino acid type II transmembrane containing a 28 amino acid cytoplasmic domain, a 21 amino acid transmembrane domain, and a 205 amino acid extracellular domain (ECD). The human 41BBL ECD shares 32 % and 35 % a.a. identity with murine and rat ECD.
