A20069I_A647_ACE2_Antibody_2_122120
Human paraffin-embedded testis tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Tris-Buffered Saline 1X (1.0M, pH 7.4) at 95°C for 40 minutes. Tissue was washed with PBS/0.05% Tween 20 twice for five minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/mL anti-human ACE2 (clone A20069I) Alexa Fluor® 647 (red) at 4°C overnight. Nuclei were counterstained with DAPI (green). The image was captured with a 10X objective.

Description

Angiotensin-converting enzyme 2 (ACE2) is a type one transmembrane protein, which shares approximately 60% homology with ACE. The predicted human ACE2 protein sequence consists of 805 amino acids, including an N-terminal signal peptide, a single catalytic domain, a C-terminal membrane anchor, and a short cytoplasmic tail. ACE2 catalyzes the cleavage of angiotensin I into angiotensin 1-9, and angiotensin II into the vasodilator angiotensin 1-7 involved in vasoconstriction. Recently, ACE2 has been shown to be a functional receptor for the spike glycoprotein of the human coronavirus HCoV-NL63 and the human severe acute respiratory syndrome coronaviruses, SARS-CoV and SARS-CoV-2 (COVID-19 virus). Based on recent single-cell RNA sequencing (scRNA-Seq) database, high ACE2 RNA expression was identified in type II alveolar cells (AT2) of lung, esophagus upper and stratified epithelial cells, kidney proximal tubule cells, enterocytes in ileum and colon, cholangiocyte in bile duct, myocardial cells in heart, and endothelium and vascular smooth muscle cells.
