Luciferase Reporter Cell Line - KGN

KGN is a well-established human ovarian granulosa-like tumor cell line, originally isolated from an adult granulosa cell tumor. It is now widely utilized as an in vitro model in studies investigating granulosa cell biology, ovarian endocrine function, follicular development, and the pathogenesis of granulosa cell tumors. KGN cells retain several key characteristics of differentiated granulosa cells, including the expression of critical steroidogenic enzymes and ovarian functional markers, responsiveness to follicle-stimulating hormone (FSH)-mediated signaling, and the capacity to support research into hormonal regulation, cell proliferation, apoptosis, and gene expression within the ovarian microenvironment. The KGN Luciferase Reporter Cell Line is an engineered derivative of the parental KGN cell line, modified to stably express a luciferase reporter gene. Through stable genomic integration and rigorous selection, this reporter cell line maintains consistent luciferase activity across multiple passages, enabling researchers to monitor cell number, viability, growth dynamics, and cellular responses using highly sensitive bioluminescence detection methods.

The KGN Luciferase Reporter Cell Line is applicable to a broad spectrum of research fields, and is particularly well-suited for studies requiring the quantitative and sensitive monitoring of KGN cellular responses. In the realm of drug discovery and compound screening, researchers can utilize KGN-Luc cells—by measuring luciferase activity as a surrogate marker for viable cell count—to assess the impact of candidate molecules, natural products, hormones, signaling pathway inhibitors, or cytotoxic agents on the viability and proliferative capacity of granulosa cell tumor cells. This application facilitates the efficient execution of dose-response analyses, time-course studies, and comparative evaluations across various treatment conditions. In oncology-related research, this cell line serves as a powerful tool for investigating the mechanisms of granulosa cell tumor progression, tumor cell survival, signaling pathway regulation, and therapeutic sensitivity. Given the exceptional sensitivity of bioluminescence detection and its compatibility with multi-well plate formats, the KGN-Luc cell line is also highly suitable for medium-to-high-throughput screening workflows, thereby reducing assay turnaround times while enhancing the consistency of quantitative results.
