Luciferase Reporter Cell Line - IPEC-J2

IPEC-J2 is a non-transformed porcine intestinal epithelial cell line originally isolated from the jejunum of a neonatal piglet. Because it retains many characteristics of normal intestinal epithelial cells—including epithelial morphology, the ability to form tight junctions, cellular polarity, and responsiveness to microbial, nutritional, inflammatory, and toxicological stimuli—IPEC-J2 has become a widely utilized in vitro model for studying porcine intestinal physiology and host-pathogen interactions. The IPEC-J2 Luciferase Reporter Cell Line is an engineered reporter cell model constructed by stably introducing a luciferase reporter gene into the IPEC-J2 cellular background. Through stable genomic integration and selection, this cell line maintains consistent levels of luciferase expression during routine culture, thereby enabling sensitive, quantitative, and reproducible detection of cellular responses using luminescence-based assays.

The IPEC-J2 Luciferase Reporter Cell Line is applicable to a wide range of cell-based assays, particularly those requiring the sensitive and quantitative monitoring of biological changes within intestinal epithelial cells. It is especially valuable for assessing the effects of nutrients, probiotics, prebiotics, phytochemicals, antimicrobial compounds, mycotoxins, inflammatory mediators, and candidate veterinary drugs on porcine intestinal epithelial cell function. Researchers can utilize this reporter cell line to evaluate cell viability, cytotoxicity, signal pathway activation, promoter regulation, stress responses, inflammatory signaling, infection-related responses, and the protective effects of bioactive compounds under controlled in vitro conditions. In the context of host-microbe interaction studies, IPEC-J2-Luc supports exploratory research involving pathogenic bacteria, commensal microbes, microbial metabolites, or bacterial toxins, assisting researchers in quantitatively analyzing epithelial cell responses following exposure or treatment. In the context of intestinal barrier research, this cell line can be integrated with assays such as transepithelial electrical resistance, tight junction protein expression, cytokine production, oxidative stress, and permeability measurements, thereby facilitating a more comprehensive and in-depth understanding of the integrity of epithelial structures and the mechanisms regulating their function.
