Data Sheet

Background: Angiotensin converting enzyme (ACE2) receptors locate in the human oral pharynx and upper airway where the high replication rate of Corona virus happens more easily. ACE2 has been confirmed as the cause of SARS-CoV-2 internalization in concert with TMPRSS2 (transmembrane protease serin 2). TMPRSS2 facilitates ACEs cell entry by priming the spike S protein of the virus. Therapeutic strategies that focus on the biology of ACE2 and TMPRSS2 may become beneficial for the treatment of lung disease.

Application: Functional assays

Figure 1. Dose-dependent inhibition of protease activity, measured w ith fluorogenic peptide substrate specific to ACE2 (a) and TMPRSS2 (b) Figure 2. Receptor expression on cell surface measured by flow cytometry (FACS) using anti-Flag antibody (a) and primary antibody Rb mAb to HA-tag and secondary antibody R- Phycoerythrin conjugate (b). Thin line: parental cells; thick line: receptor-expressing cells.
