Source

Species:
Human
Accession Number:
  • Q9BYF1
Expressed Region:
Gln18-Ser740 (Extracellular domain)
Protein Name & Synonyms:
ACE2, Angiotensin-converting enzyme 2, ACE-related carboxypeptidase, ACEH, Metalloprotease MPROT15

Preparation

Expression System:
Human embryonic kidney 293 (HEK293) cells
Conjugation/Tag:
C-terminal his-tag
Molecular Weight (kDa):
Recombinant protein product has a calculated molecular mass of ∼83 kDa. Due to the abundant glycosylation, it migrates as approximately 90 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. See deglycosylation analysis image below.
SDS-PAGE Image
SDS-PAGE
Figure 1. Deglycosylation of purified recombinant proteins. Purified proteins were untreated (Lane 2) or treated with Protein Deglycosylation Kit under native (Lane 3) or reducing (Lane 4) conditions. Deglycosylation treatment resulted in a mobility shift of the protein to produce one major band at the expected size, thus indicating that the untreated recombinant protein (Lane 2) was glycosylated.

Binding Function
Binding Function
The product S1 RBD (Cat. 230-30162) was coated in 96 well plate and incubated with the serial diluted human ACE2 protein (Raybio, Cat. 230-30165). The bound ACE2 was detected by anti-ACE2 antibody using ELISA. The calculated EC50 is 4.23-9.26 ng/mL.
