Active Recombinant Human CD40 protein, His-tagged

• Cat.No.: CD40-2221H
• Product Overview: Recombinant Human CD40 (Met1-Arg193) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Met1-Arg193
• Form: Lyophilized from sterile PBS, pH 7.4
• Bio-activity: Measured by its binding ability in a functional ELISA. Immobilized recombinant human CD40 at 2 μg/ml (100 μl/well) can bind biotinylated human CD40L with a linear range of 15.6-500 ng/ml.
• Molecular Mass: The secreted recombinant human CD40 comprises 184 amino acids with a predicted molecular mass of 20.7 kDa. As a result of glycosylation, rhCD40 migrates as an approximately 32 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE. > 90 % as determined by SEC-HPLC.
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
