摘要
A simple and effective method for validation of antibody labelling procedure as well as for optimal conjugate dilution assessment based on electrochemical detection is presented. Enzyme alkaline phosphatase and core-shell CdSe/ZnS quantum dots are used as sensitive tag exploitable as detection tool of antibody-antigen complex in magnetic microbead-based immunoassays. Square-wave voltammetry for detection of the electroactive product that is induced by conversion of appropriate substrate by alkaline phosphatase and square-wave anodic-stripping voltammetry for signal of Cd in case of quantum dots, respectively, was elected. Anti-Apo E IgG antibodies were selected as model molecules for method optimizations. [GRAPHICS] .
