Luciferase Reporter Cell Line - LS 174T

LS 174T is a human colorectal adenocarcinoma cell line derived from a primary colon tumor. It is widely utilized as an in vitro model for investigating colorectal cancer biology, epithelial tumor characteristics, tumor progression, drug response, and gastrointestinal oncology. These cells exhibit an epithelial-like morphology and retain various features associated with intestinal cancer, rendering them highly valuable for studies involving colon cancer signaling pathways, tumor cell proliferation, differentiation, migration, invasion, and therapeutic sensitivity. The LS 174T Luciferase Reporter Cell Line is an engineered reporter cell model constructed by stably introducing a luciferase reporter gene into the parental LS 174T cell line. This stable expression capability enables the cells to generate a measurable luminescent signal upon the addition of an appropriate luciferase substrate. Compared to transient reporter systems, a stably integrated luciferase reporter system offers more consistent signal output, superior reproducibility, and greater suitability for long-term experiments and repetitive assays.

The LS 174T Luciferase Reporter Cell Line is broadly applicable across various fields of cancer research and drug discovery. In in vitro studies, it can be employed for cell proliferation assays, cytotoxicity testing, compound screening, dose-response assessments, and time-course analyses of anti-tumor activity. Researchers can treat these cells with chemotherapeutic agents, targeted inhibitors, biologics, natural products, immunomodulatory compounds, or combination therapies, and subsequently quantify the luminescent signal to assess changes in the number of viable cells. Compared to traditional colorimetric or endpoint-based cell viability assays, this method typically offers higher assay speed and sensitivity—advantages that are particularly pronounced when conducting multi-time-point analyses or screening large compound libraries. Furthermore, this cell line supports the investigation of colorectal cancer signaling pathways by providing quantitative readouts following genetic manipulation, pathway inhibition, or exposure to microenvironmental stimuli.
