Achieving reliable, quantitative hormone detection in immunoassays
5 Mar 2026This technical note describes how recombinant human hormones produced in HEK293 cells can enable reliable and quantitative hormone detection in immunoassays. The Native Antigen Company demonstrates how recombinant versions of key hormones, including hCG, FSH, TSH, prolactin, and SHBG, provide improved lot-to-lot consistency, scalability, and biosafety compared with traditional pituitary-derived reagents. Benchmarking against WHO international standards confirms their suitability for immunoassay calibration, diagnostic assay development, and large-scale manufacturing.

ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.ImmunoassayImmunoassays are laboratory tests that utilize antibody-antigen interactions to detect specific substances. They are widely used in diagnostics for detecting diseases, drug testing, and environmental monitoring. These assays offer rapid, sensitive, and precise detection of biomarkers, making them invaluable in clinical and research labs.

The assay should be able to characterize novel compounds and measure the potency of these compounds against a validated biological target.
