Active Recombinant Human CD40 protein, hFc&His-tagged

• Cat.No.: CD40-174H
• Product Overview: Recombinant Human CD40 protein(Glu21-Arg193), fused with C-terminal hFc and His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc&His
• Protein Length: 21-193 aa
• Form: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
• Bio-activity: Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human CD40 Ligand at 2 μg/mL (100 μL/well) can bind Recombinant Human CD40 with a linear range of 224-898 ng/mL.
• Molecular Mass: 45.95 kDa
• Endotoxin: < 0.1 EU/μg of the protein by LAL method.
• Purity: ≥ 95 % as determined by SDS-PAGE; ≥ 90 % as determined by HPLC.
• Storage: Store at -20°C.Store the lyophilized protein at -20°C to -80°C up to 1 year from the date of receipt.After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C for up to 1 week.
• Reconstitution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
