    摘要: The present invention relates to dimeric pentadentate chelators with exceptionally strong binding of metal ions, for detection, immobilization and purification of biomolecules. Dimeric chelators offer a cooperativity of binding of two adjacent immobilized metal ions simultaneously to a histidine-tagged biomolecule, which gives advantageous properties regarding strength of binding compared to a corresponding monomer chelator. In addition, a dimer increases the selectivity (ease of separation) against non-tagged biomolecules with low metal-ion affinity.The dimeric pentadentate chelator according to the invention has the following general formula: whereinSc is a scaffold or a connecting structure that contains at least two functional groups enabling coupling of two pentadentate chelators (PD), andPD is a pentadentate chelator having the formula:

    摘要: The present invention relates to a method for the quantitative determination of the amount of one or more biomolecules, such as proteins or polypeptides, in one or more samples by utilising sample unique tagging reagents. More specifically, the method comprises steps of providing at least two samples; reacting biomolecules present in each sample with a sample unique mass tagging reagent to provide sample unique mass tagged forms thereof; combining tagged forms present in each sample to provide a single sample; coseparating, from the resulting sample, a mix of mass tagged forms of each of said biomolecules into different fractions; subjecting, for each fraction, the mix to mass spectrometry to obtain a mass spectrum; and determining from signals in each mass spectrum, the amount of the biomolecule corresponding to the spectrum in at least one of said samples relative to the amount of the same biomolecule in at least one of the remaining samples. In an advantageous embodiment, the separation step is a gel electrophoresis step. In some cases, it may be advantageous to also include a step of digesting biomolecules, such as protein(s).
