  • Title: Silver sol immunoagglutination assay for determination of human IgG.
    Author: Gasparyan VK.
    Journal: Colloids Surf B Biointerfaces; 2010 Oct 15; 80(2):180-3. PubMed ID: 20599366.
    Abstract:
    Immunoagglutination properties of silver nanoparticles sensitized with antibodies to human IgG for determination of IgG were studied. Effects of various pH on sensitization and consequent immunoagglutination process were investigated. It was shown that the best results were obtained when sensitization and immunoagglutination were conducted at isoelectric point of IgG molecule. It was demonstrated that immunoassay with colloidal silver nanoparticles provides the detection of antigen in wide range of concentrations.
