Findings from Nanjing University in the Area of Immunoglobulins Described

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Immunology have been published. According to news reporting originating from Jiangsu, People's Republic of China, by NewsRx correspondents, research stated, "Magnetic Fe70Co30 nanoparticles with a cubic shape and a mean size of 15 +/- 1.5 nm were fabricated using a magnetron-sputtering-based gas phase condensation deposition method. The particles had a high saturation magnetization of 220 emu/g, which is much higher than that of commercially available iron oxide nanoparticles."

Our news editors obtained a quote from the research from Nanjing University, "The FeCo nanoparticles were modified by 3-aminopropyltriethoxy silane and subsequently activated by glutaraldehyde, leading to successful attachment of aldehyde groups onto nanoparticle surfaces. Three proteins, namely streptavidin, PAPP-A antibody and Nectin-4 antibody, were immobilized on glutaraldehyde activated FeCo nanoparticles, and their loading levels were quantitatively evaluated. Our results show that loading capabilities are 95 mu g of streptavidin, 128 p.,g of PAPP-A, and 125 mu g of Nectin-4 antibody per milligram of FeCo nanoparticles, and that the three immobilized proteins retain their binding bioactivity."

According to the news editors, the research concluded: "The protein-FeCo conjugates may find valuable applications involving magnetic separation and purification of proteins and cells, and the magnetic detection of biomolecules."
