The invention provides a method of separating proteins and peptides of a sample comprising contacting the sample with a Pt coordination compound stably associated with a substrate. The Pt 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 Pt coordination compounds, including their modified, unmodified, processed and unprocessed forms. Also disclosed are methods, systems and kits for using the Pt coordination compound. In certain embodiments the purified proteins and/or peptides may be analyzed using, for example, mass spectrometry to identify and quantify proteins and/or peptides in a sample, such as a proteome or peptidome.
