E3/Estriol ELISA Kit

Assay Genie offers a competitive ELISA kit for the quantitative detection of Estriol (E3), a key estrogen hormone primarily produced during pregnancy, where its levels can indicate fetal health and development. The kit is designed for research and diagnostic applications, with relevance to reproductive health, endocrine disorders, and pregnancy monitoring, and is available in multiple configurations.

The assay uses a competitive immunoassay format with a colorimetric readout. Reported performance characteristics vary by configuration: one variant reports a sensitivity of 0.469 ng/mL and a range of 0.781–50 ng/mL, while another reports a sensitivity of 3.7 pg/mL and a range of 7.81–500 pg/mL. A further configuration offers a range of 3.12–200 ng/mL. Recovery and linearity data are provided for serum, plasma, and urine matrices depending on the variant.

Acceptable sample types include serum, plasma, and other liquid samples such as cell culture supernatant, cell or tissue lysate, and urine. Reactivity is described as Universal or General across configurations, and the kit is stored at 2–8°C in sealed conditions without cryopreservation.
