Monitoring of the non-steroid anti-inflammatory drug indomethacin: development of immunochemical methods for its purification and detection.

The present research focused on the development of an immunoassay and an immunochemical sol-gel-based immunoaffinity purification (IAP) method for purification and detection of the non-steroid anti-inflammatory drug (NSAID) indomethacin (IMT). A polyclonal antibody (Ab) for IMT was generated, and two sensitive microplate assays for the detection of IMT were developed (termed OV and HRP formats), based on the enzyme-linked immunosorbent assay (ELISA) method. The limits of detection of the assays were 15 ± 1.

Monitoring of progestins: development of immunochemical methods for purification and detection of levonorgestrel.

A polyclonal antibody (Ab) for the progestin levonorgestrel (LNG) was generated, and immunochemical assays for its detection, clean-up and concentration were developed. A highly specific microplate diagnostic assay for the detection of LNG was developed that used the enzyme linked immunosorbent assay (ELISA) method. The LNG ELISA developed was sensitive and reproducible; it exhibited I(50) and I(20) values of 3.
