Recombinant Human CD40 protein, His-Avi-tagged, Biotinylated

• Cat.No.: CD40-2222H
• Product Overview: Biotinylated Recombinant Human CD40 protein(P25942)(Glu21-Arg193), fused with C-terminal His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: Glu21-Arg193
• Tag: C-His-Avi
• Conjugation/Label: Biotin
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Biotinylated Human CD40, His Tag at 1μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human CD40 Ligand (Trimer), hFc Tag with the EC50 of 9.5ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 22.1 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result.
• Endotoxin: Less than 1EU per μg by the LAL method.
• Purity: > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
• Storage: Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
• Reconstitution: Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
• Conjugation: Biotin
