Progesterone-3-HRP Antigen

The Antibodies.com Progesterone-3-HRP Antigen is a ready-to-use enzymatic conjugate supplied as a 1 ml liquid formulation. In this construct, the steroid hormone progesterone is covalently attached at the C3 position to horseradish peroxidase (HRP), creating a reporter-labeled antigen suited to competitive immunoassay workflows. The HRP tag enables sensitive enzymatic readout when paired with substrates such as TMB or other chromogenic reagents, supporting quantitative measurement of progesterone in research samples.

Typical research applications include competitive ELISA plate development for steroid hormone profiling, veterinary reproductive studies, and academic investigation of the estrous cycle, pregnancy monitoring, and corpus luteum function. The conjugate is also useful as a tracer reagent in lateral flow assay prototyping and microfluidic immunoassay development. Researchers should optimize the working dilution against their specific antibody pair, since HRP activity and the stability of the steroid linkage shape the competitive binding curve.

This product is intended for research use only and is not approved for clinical diagnostic use. The liquid conjugate is provided as a 1 ml vial, allowing preparation of working aliquots to limit freeze-thaw cycles on the stock solution and preserve enzymatic activity over time.
