Achieving reliable, quantitative hormone detection in immunoassays

This 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.
