Human TRPM4 Stable Cell Line - HEK293

The TRPM4 gene encodes the transient receptor potential melastatin 4 protein, a calcium-activated non-selective cation channel that conducts monovalent cations such as sodium and potassium while being impermeable to calcium ions. This channel is widely expressed in cardiac tissue, pancreatic beta cells, immune cells, and neuronal populations, where it regulates membrane depolarization and calcium signaling dynamics. The Human TRPM4 Stable Cell Line - HEK293 is generated by transfecting the human TRPM4 gene into the HEK293 host cell line, followed by antibiotic selection to establish a homogenous population that stably and reproducibly expresses functional TRPM4 channels at the plasma membrane. This stable cell line eliminates the need for repeated transfections and provides consistent channel expression levels across passages, making it a reliable and convenient tool for TRPM4-related research.

This cell product is primarily designed for use in ion channel drug discovery and pharmacological profiling. Researchers can employ the Human TRPM4 Stable Cell Line - HEK293 in manual or automated patch-clamp electrophysiology studies to characterize channel kinetics, voltage dependence, and calcium sensitivity, as well as to screen compound libraries for novel TRPM4 inhibitors or activators. The stable expression system also supports fluorescence-based membrane potential assays using dyes, enabling high-throughput functional screening in a multi-well plate format. Beyond drug discovery, this cell line is valuable for investigating TRPM4-mediated signaling pathways, including its role in calcium influx regulation, cell volume control, and excitability modulation in heterologous expression systems. It can also be used to study disease-associated TRPM4 mutations identified in conditions such as progressive familial heart block or immune disorders, providing a defined cellular background for structure-function analysis. Additionally, the line may serve as a positive control for TRPM4 antibody validation or Western blotting workflows, and it can support downstream applications such as co-immunoprecipitation to identify channel-interacting proteins.
