AccuSift provides high-performance competitive immunoassay antibody pairs for 19-Nortestosterone with exceptional lot-to-lot consistency. Optimized for IVD kit development (Lateral Flow, CLIA, ELISA, POCT), these antibodies offer high affinity and specificity to facilitate rapid detection.19-Nortestosterone is a synthetic androgen steroid hormone. It reacts with sulfuric acid to produce a reddish-brown color with yellow-green fluorescence and forms a white precipitate with silver nitrate solution. It is primarily used as a pharmaceutical raw material and chemical intermediate.Derivatives of 19-Nortestosterone are utilized in progestin formulations. Clinically, they are used to treat conditions such as dysfunctional uterine bleeding, endometriosis, and for contraception. Representatives include norethisterone, levonorgestrel, and desogestrel, which are key compounds in first, second, and third-generation progestins respectively.
