Anti-Estriol (E3) Antibody

Manufactured by Antibodies.com, this mouse monoclonal primary antibody is raised against Estriol (E3) and supplied as a 1 mg Protein A–purified IgG reagent in unconjugated form, ready for direct coating or conjugation in immunoassay workflows. The clone was generated using Estriol conjugated to a carrier protein as immunogen, and the antibody has been validated for use in ELISA, where it is reported to provide sensitive detection of unconjugated estriol (uE3) with limited cross-reactivity to related steroids such as estradiol (E2), estrone (E1), and estriol sulfates/glucuronides. Because it is a monoclonal, batch-to-batch consistency is high, supporting reproducible performance in quantitative assays. The recommended storage condition is 2–8 °C for short-term use and –20 °C for longer-term retention, with the purified IgG supplied in a buffer suitable for dilution into standard assay buffers. Researchers developing prenatal screening or steroid profiling assays will appreciate the specificity profile and the convenience of a 1 mg pack size, which provides ample material for plate-coating optimization and downstream assay development.
