Recombinant Human CD40, Fc-tagged, Biotinylated

Cat.No.: CD40-577H
Product Overview: The recombinant human CD40-Fc fusion is expressed as a 401 amino acid protein consisting of Glu21 - Arg193 region of CD40 (UniProt accession #P25942) and a C-terminal Fc from human IgG1, which exists as a dimer under non-reducing conditions.
Source: Human cells
Species: Human
Tag: Fc
Form: Supplied at 0.5 mg/ml in sterile PBS pH7.4 (carrier & preservative free). The purified recombinant protein was labeled with Biotin (3-5 Biotin per molecule).
Bio-activity: Binds to its ligand CD40L/CD154 and inhibits CD40L--induced signaling activity including NF-κB activation and proliferation of human B cells.
Molecular Mass: Calculated molecular mass (kDa): 44.7; Estimated by SDS-PAGE under reducing condition (kDa): 55-60
Endotoxin: <0.1 eu per 1 μg of purified recombinant protein determined by the
Purity: >95% judged by SDS-PAGE under reducing condition
Storage: The product is shipped at 4°C. Upon receipt, centrifuge the product briefly before opening the vial. It is recommended to store small aliquots at the temperature below –20°C for long-term storage and the product is stable for 3 months. The undiluted protein can be stored at 4°C for no more than 2 weeks. Avoid repeated freeze-thaw cycles.
