    摘要: The invention provides a method of separating proteins and peptides of a sample comprising contacting the sample with a Pd coordination compound. The Pd coordination compound binds to sulfur and/or nitrogen groups and thus is useful for purifying biomolecules comprising cysteine, methionine, histidine amino acids or derivatized amino acids/residues comprising sulfur or nitrogen groups which bind to coordination sites on the Pd coordination compounds. The invention also relates to methods, systems and kits for using the Pd coordination compound.

    摘要: Apparatus and methods are disclosed for concentrating one or more components in a fluid effluent, which comprises fractions comprising separated components of interest. The fluid effluent is passed through a concentration device comprising a hollow element comprising a wall at least a portion of which is porous wherein the hollow element is disposed in the interior of a hollow liner. Fluid effluent molecules are permitted to permeate through the wall of the hollow element so that component molecules are concentrated in remaining effluent, which exits the concentration device. The component or components may then be detected.

    摘要: Apparatus and methods are disclosed for digesting a biopolymer in a medium. The medium is disposed adjacent a wall of a hollow element wherein at least a portion of the wall is porous. The medium is then exposed to digestion conditions to cleave the biopolymer into fragments. The fragments are permitted to permeate through the wall of the hollow element. In some embodiments a surface of a wall of the hollow element comprises a digestion agent. In some embodiments the hollow element is disposed within a hollow liner. For analysis and identification purposes, the fragments may be separated and/or detected.

    摘要: A method of analyzing a polynucleotide using matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS) is described. The method includes obtaining the polynucleotide bound to a substrate via a linker moiety having a triaryl methyl linker group. The polynucleotide bound to the substrate is then contacted with a matrix material and analyzed by MALDI-MS. During the MALDI-MS analysis, laser radiation is directed at the matrix material, thereby exciting the matrix material and causing cleavage of the linker moiety. Ions generated as a result of this excitation and cleavage process are then analyzed to provide information about the polynucleotide.
