ACE2/VERO Stabiele cellijn

ACE2/VERO Stable Cell Line is a stably transfected Vero E6 cell line which expresses human angiotensin-converting enzyme 2 (ACE2) . ACE2 is a type I transmembrane metalloenzyme located on the outer surface of endothelial cells in the lung, arteries, heart, kidney and intestines. ACE2 cleaves the carboxyl-terminal amino acid phenylalanine from angiotensin II and hydrolyses it into the vasodilator angiotensin. ACE2 also serves as an entry receptor for some coronaviruses including HCoV-NL63, SARS-CoV and SARS-CoV-2 as the virus that causes COVID-19.

Functional Assay

Each vial contains 2 ~ 3 x 10^6 cells in 1 ml of 90% FBS + 10% DMSO.

Dry ice

Immediately upon receipt, store in liquid nitrogen.

Application: Screen for antibodies of human ACE2 through Flow Cytometry. Protein binding study. Culture conditions: Cells should be grown at 37°C with 5% CO2 using DMEM medium (w/ L-Glutamine, 4.5g/L Glucose and Sodium Pyruvate) supplemented with 10% heat-inactivated FBS and 1% Pen/Strep, plus 250 μg/ml of Hygromycin. It is recommended to quickly thaw the frozen cells upon receipt or from liquid nitrogen in a 37°C water-bath, transfer to a tube containing 10 ml of growth medium without Hygromycin, spin down cells, resuspend cells in pre-warmed growth medium without Hygromycin, transfer resuspended cells to T25 flask and culture in 37°C-CO2 incubator. ve the T25 flask in the incubator for 1~2 days without disturbing or changing the medium until cells completely recover viability and become adherent. Once cells are over 90% adherent, remove growth medium and passage the cells through trypsinization and centrifugation. At first passage, switch to growth medium containing Hygromycin. Cells should be split before they reach complete confluence. To passage the cells, detach cells from culture vessel with Trypsin/EDTA, add complete growth medium and transfer to a tube, spin down cells, resuspend cells and seed appropriate aliquots of cells suspension into new culture vessels. Subcultivation ration = 1:10 to 1:20 weekly. To achieve satisfactory results, cells should not be passaged over 16 times.
