ACE2 Gene Knockout NCI-H520 Cell Strategy
CRISPR-U™ technology (CRISPR based), developed by Ubigene, is more efficient than general
CRISPR/Cas9 technology in double-strand breaking and homologous recombination. With CRISPR-U™, Ubigene has
successfully edited over 3000 genes on more than 100 types of cell lines.
Objective
To create a Human ACE2 Knockout
model in NCI-H520 cell line by
CRISPR-U™-mediated
genome
engineering.
Target gene info 
| Official symbol | ACE2 |
| Gene id | 59272 |
| Organism | Homo sapiens |
| Official full symbol | angiotensin I converting enzyme 2 |
| Gene type | protein-coding |
| Also known as | ACEH |
| Summary | 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. ACE2 is known to be expressed in various human organs, and its organ- and cell-specific expression suggests that it may play a role in the regulation of cardiovascular and renal function, as well as fertility. In addition, the encoded protein is 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, the causative agent of coronavirus disease-2019 (COVID-19). |

Cell line info
| Cell name | NCI-H520 |
| Tissue | lung |
| Organism | Human |
| Morphology | epithelial |
| Culture properties | adherent |

| Derivation | The NCI-H520 cell line was derived by A.F. Gazdar and associates in 1982 from a sample of a lung mass taken from a patient with squamous cell carcimoma of the lung. |
| Complete growth medium | Complete Growth MediumThe base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: · fetal bovine serum to a final concentration of 10%This medium is formulated for use with a 5% CO2 in air atmosphere. ATCC tested fetal bovine serum is available as ATCC Catalog No. 30-2020 (500 mL) and ATCC Catalog No. 30-2021 (100 mL). |
| Subcultivation ratio | A subcultivation ratio of 1:3 to 1:6 is recommended Medium Renewal: 2 to 3 times per week |
