Fudan University Reports Findings in Peptides and Proteins

February 18, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Peptides and Proteins is the subject of a report. According to news originating from Shanghai, People's Republic of China, by NewsRx correspondents, research stated, "In this work, core-shell magnetic metal organic framework (MOF) microspheres were successfully synthesized by coating magnetite particles with mercaptoacetic acid and subsequent reactions with ethanol solutions of Cu(OAc)2 and benzene-1,3,5-tricarboxylic acid (designated as H3 btc) alternately. The resulting Fe3 O4 @[Cu3 (btc)2 ] possess strong magnetic responsiveness."

Our news journalists obtained a quote from the research from Fudan University, "We applied the novel nanocomposites in the enrichment of low-concentration standard peptides, peptides in MYO and BSA tryptic digests and in human urine in combination with MALDI-TOF MS analysis for the first time. In addition, the Cu3 (btc)2 MOF shells exhibit strong affinity to peptides, thus providing a rapid and convenient approach to the concentration of low-abundance peptides. Notably, peptides at an extremely low concentration of 10 pM could be detected by MALDI-TOF MS after enrichment with the magnetic MOF composites."

According to the news editors, the research concluded: "In brief, the facile synthesis and efficient enrichment process of the Fe3 O4 @[Cu3 (btc)2 ] microspheres make them promising candidates for the isolation of peptides in even complex biological environments."
