| 英文摘要 | Characterization of silver-associated proteins is important to elucidate underlined mechanisms of silver-containing materials against microbes. Gel electrophoresis based methods are the most popular and basic strategy for the analysis of biomolecules, i.e., proteins and nucleic acids. It solely provides molecular weights of analytes. Extending the method from molecular weight to elemental composition is highly desired when investigating metal-containing molecules. Herein, a gel electrophoresis based method combining native sodium dodecyl sulfate-polyacrylamide gel electrophoresis (native SDS-PAGE), fluorescent staining, and inductively coupled plasma mass spectrometry (ICP-MS) strategy was developed for separation and detection of silver-associated proteins. Two home-made silver-labeled proteins, carbonic anhydrase and ovalbumin, were used for validation of the strategy performance. Silver-associated proteins in Pseudomonas aeruginosa and Staphylococcus aureus treated with silver nanoparticles were further characterized by this method. Some well-known and new proteins were identified to associate to silver in both P. aeruginosa and S. aureus, demonstrating the feasibility of the developed strategy. In conclusion, the current study provides a convenient method for readily identification of silver-associated proteins in biological samples. (C) 2019 Elsevier B.V. All rights reserved. |
