The Signosis CD19-Expressing CHO Stable Cell Line is a genetically engineered Chinese Hamster Ovary (CHO) cell line designed to provide a reliable source of human CD19 antigen for CAR-T cell research, immunotherapy development, and antigen-specific cell-based functional assays.
 
Developed through lentiviral transduction and single-cell clone selection, this stable cell line expresses CD19 on the cell surface, enabling recognition by anti-CD19 chimeric antigen receptor (CAR)-expressing T cells.
 
The CD19-Expressing CHO Stable Cell Line serves as a complementary target cell model for evaluating antigen-dependent CAR activation and can be used together with the Signosis Anti-CD19 CAR/NFAT Luciferase Reporter Jurkat Stable Cell Line (cat# SL-0138) in co-culture assays.
