Claudin18,2/HEK293 Stabiele cellijn

Claudin 18.2/HEK293 Stable Cell Line is a stably transfected HEK293 cell line which expresses human claudin 18.2 (CLDN18.2) . CLDN18.2 is a highly selective marker protein that is exclusively expressed in differentiated gastric mucosal membrane epithelial cells. Abnormal expression of CLDN18.2 has been observed during the occurence and development of various primary malignat tumors such as gastric cancer, breast cancer, colon cancer and liver cancer. CLDN18.2 has become a significant biomarker for targeted therapy in different cancers, and a monoclonal antibody against CLDN18.2 such as Anti-CLDN18.2 (zolbetuximab biosimilar, Abeomics, Cat. No.: 12-9134) is an example utilized in the immunotherapy targeting CLDN18.2.

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 Claudin 18.2 through Flow Cytometry. Culture conditions: Cells should be grown at 37oC 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 10 μg/ml of Blasticidin. It is recommended to quickly thaw the frozen cells upon receipt or from liquid nitrogen in a 37oC water-bath, transfer to a tube containing 10 ml of growth medium without Blasticidin, spin down cells, resuspend cells in pre-warmed growth medium without Blasticidin, transfer resuspended cells to T25 flask and culture in 37oC-CO2 incubator. Leave 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 Blasticidin. 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.
