Active Recombinant Human ACE2 protein, His-tagged

• Cat.No.: ACE2-736H
• Product Overview: Active Recombinant Human ACE2 protein(Q9BYF1-1)(Gln18-Ser740), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 18-740 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4).
• Bio-activity: Immobilized Human ACE2, His Tag at 5μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated SARS-COV-2 Spike RBD, hFc Tag with the EC50 of 27.2ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 84.7 kDa. Due to glycosylation, the protein migrates to 85-110 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 1 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
• Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
