GFP Reporter Stable Cell Line-HeLa

HeLa is the oldest and most widely used immortalized human cell line, originally isolated in 1951 from a cervical adenocarcinoma biopsy taken from Henrietta Lacks. These epithelial cells grow adherently with a doubling time of roughly 20 to 24 hours and are known for their remarkable durability and prolific nature in culture. The HeLa karyotype is hypertriploid, typically containing 76 to 80 chromosomes, and the cells carry integrated human papillomavirus type 18 sequences. The GFP Reporter Stable Cell Line-HeLa is a genetically modified derivative that stably expresses green fluorescent protein under the control of a constitutive or inducible promoter. This engineered line was generated through transfection and antibiotic selection to create a homogeneous population that consistently produces GFP, enabling real-time visualization of cellular events without the need for repeated transfection or staining steps.

This stable reporter cell line is widely used in drug screening, gene expression analysis, and signal transduction studies. Because GFP fluorescence can be monitored live and non-invasively, researchers can track changes in promoter activity, protein localization, or cell behavior over time in a high-throughput format. The line is particularly valuable for testing compounds that modulate transcriptional activity, as GFP intensity serves as a direct readout of pathway activation or inhibition. It also supports applications in virology, where GFP expression allows rapid detection of viral infection or replication kinetics. In cancer biology, these cells are used to study tumor cell proliferation, migration, and response to therapeutic agents in both 2D and 3D culture models. The stable integration of the GFP reporter eliminates the variability associated with transient transfection, making this cell line a reliable and reproducible tool for long-term experiments and large-scale screening campaigns.
