Streptavidin-polyvinylamine conjugates labeled with a europium chelate : Applications in immunoassay, immunohistochemistry, and microarrays
Background: The favorable properties of lanthanide chelates compared with conventional fluorescent probes have attracted considerable interest. A Eu3+ chelator, 4,7-bis(chlorosulfophenyl)-1,10-phenanthroline-2,9-dicarboxylic acid (BCPDA), has been synthesized previously. Methods: We here describe immunoassay, immunohistochemistry, and microarray applications of a new streptavidin-based universal p
