Human ACE2/ACEH Protein

Product Info

Recombinant Human ACE2/ACEH Protein is expressed from Expi293 with His tag at the C-terminal. It contains Gln18-Ser740.[Accession | Q9BYF1-1]

Molecular Weight

The protein has a predicted MW of 84.7 kDa. Due to glycosylation, the protein migrates to 85-110 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Supplied as 0.22μm filtered solution in PBS (pH 7.4).


The product should be stored at -70℃. Please do not repeated freeze-thaw cycles.

Assay Data
Tris-Bis PAGE

Human ACE2 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SPR Data

SARS-COV-2 Spike RBD captured on Protein A chip, can bind Human ACE2, His Tag with an affinity constant of 11.9nM as determined in a SPR assay (Biacore T200).


ACE2 (Angiotensin I Converting Enzyme 2) is a Protein Coding gene. Diseases associated with ACE2 include Severe Acute Respiratory Syndrome and Neurogenic Hypertension.The protein encoded by this gene belongs to the angiotensin-converting enzyme family of dipeptidyl carboxydipeptidases and has considerable homology to human angiotensin 1 converting enzyme. This secreted protein catalyzes the cleavage of angiotensin I into angiotensin 1-9, and angiotensin II into the vasodilator angiotensin 1-7.
