Angiotensin-converting enzyme 2 (ACE2, also known as ACEH) is a transmembrane protein and acts as receptor for SARS-CoV, SARS-CoV-2 and some other coronaviruses. The large extracellular peptidase domain of ACE2 is known to interact with the spike proteins of coronaviruses. The small C-terminal collectrin-like domain (CLD) has recently been described to mediate homo-dimerization of ACE2. The main function of ACE2 is the catalytic conversion of angiotensins, thereby regulating cardiovascular homeostasis. Recombinant Human ACE2 (insect cells) protein covers amino acids Q18 to D615 of human ACE2

ELISA of Recombinant Human ACE2
. Binding of biotinylated Recombinant Human ACE2 to recombinant RBD was detected. Truncated ACE2 without CLD (triangle: insect cell–derived Miltenyi Biotec product) and full length ACE2 including CLD (square: HEK-derived Miltenyi Biotec product; circle: another commercially available product) was analyzed.

Overview

Angiotensin-converting enzyme 2 (ACE2, also known as ACEH) is a transmembrane protein and acts as receptor for SARS-CoV, SARS-CoV-2 and some other coronaviruses. The large extracellular peptidase domain of ACE2 is known to interact with the spike proteins of coronaviruses. The small C-terminal collectrin-like domain (CLD) has recently been described to mediate homo-dimerization of ACE2. The main function of ACE2 is the catalytic conversion of angiotensins, thereby regulating cardiovascular homeostasis. Recombinant Human ACE2 (insect cells) protein covers amino acids Q18 to D615 of human ACE2 excluding the C-terminal collectrin-like domain and contains a His-tag and an AviTag™. Recombinant Human ACE2 (insect cells)-Biotin is specifically biotinylated at a single site, preserving full functionality of ACE2.
