A molecularly imprinted polymer synthesized in dichloromethane, was evaluated for the selective extraction of a pharmaceutical compound from human plasma and integrated on-line with liquid chromatography. The target drug is an alpha-blocker called alfuzosin widely used for the treatment of benign prostatic hyperplasia. By a comprehensive approach of the(More)
An in-line procedure for protein analysis using a trypsin-based immobilized enzymatic reactor (IMER) coupled to LC-MS/MS has been developed. Various IMERs were synthesized and characterized by estimating the digestion yield of a pattern peptide in UV detection. Laboratory-made IMERs were optimized by studying the effect of different parameters as the nature(More)
A molecularly imprinted polymer (MIP) using zidovudine (AZT) as template and methacrylic acid as monomer was prepared. The synthesis of the MIP was performed in acetonitrile. The synthesized material was then tested for the solid-phase extraction of AZT from different media (pure organic solvents and hydro-organic mixtures). An optimised procedure was(More)
A total on-line analysis of a target protein from a plasma sample was made using a selective immunoextraction step coupled on-line to an immobilized enzymatic reactor (IMER) for the protein digestion followed by LC-MS/MS analysis. For the development of this device, cytochrome c was chosen as model protein due to its well-known sequence. An immunosorbent(More)
