Human TSHR Stable Cell Line - HEK293

Human TSHR encodes the glycoprotein-hormone G protein-coupled receptor that controls thyroid growth and thyroid-hormone synthesis. This product is a stable HEK293 cell line engineered to maintain elevated expression of human TSHR. This cell line is engineered to stably human thyroid stimulating hormone receptor (TSHR). HEK293 cells provide a well-characterized human background with robust growth, reproducible transgene expression, and broad compatibility with plate-based biochemical and imaging workflows. Stable integration reduces the experiment-to-experiment variability associated with transient transfection and supports repeated use across assay campaigns.

Functionally, the line is intended to provide consistent access to human TSHR-dependent biology. It is particularly suitable for TSH potency testing, cAMP or downstream signaling assays, characterization of stimulating or blocking autoantibodies, receptor pharmacology, and research into Graves' disease, hypothyroidism, and thyroid-targeted therapeutics. As a defined receptor-overexpression model, the cell line complements primary cells and tissue-derived systems by isolating target-dependent signaling from the complexity of mixed receptor populations. Its stable phenotype supports comparative pharmacology across compound series, biologic formats, and repeated screening campaigns, while preserving the same host-cell background for mechanistic interpretation. The model also provides a consistent framework for linking receptor occupancy to proximal signaling, receptor trafficking, and downstream cellular responses relevant to target validation and drug discovery. Receptor-focused datasets generated with this line can clarify ligand potency, efficacy, selectivity, desensitization, and internalization within a single cellular context.
