Active Recombinant Human CD40 protein, hFc-tagged

• Cat.No.: CD40-837H
• Product Overview: Recombinant Human CD40 protein(P25942)(21-193aa), fused to C-terminal hFc tag, was expressed in Mammalian cell.

Specification

• Source: Mammalian cell
• Species: Human
• Tag: hFc
• Form: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
• Bio-activity: 1. Measured by its binding ability in a functional ELISA. Immobilized CD40 at 2 μg/ml can bind CD40L, the EC50 is 3.112-3.858 ng/ml. 2. Human CD40 protein hFc tag captured on COOH chip can bind Human CD40L protein hFc and Flag tag with an affinity constant of 2.06 nM as detected by LSPR Assay.
