title: N-(Iodoacetyl)-N'-(anthraquinon-2-oyl)-ethylenediamine (IAED): a new heterobifunctional reagent for the preparation of biochips.
abstract: Design and synthesis of a new heterobifunctional reagent, N-(iodoacetyl)-N'-(anthraquinon-2-oyl)-ethylenediamine (IAED), have been described for the preparation of oligonucleotide-based biochips. The performance of the featured reagent is probed by the immobilization of thiolated and thiophosphorylated oligonucleotides on modified glass microslides via two routes (routes A and B). The immobilization procedure was accelerated by performing a chemical reaction between thiolated oligomers and the iodoacetyl moiety of the reagent under microwaves (MW), where it is completed in just 10 min. The quality of the constructed oligonucleotide microarrays was tested by performing a hybridization assay with a complementary target and subsequently used for the detection of base mismatches. The immobilized probes were found to be thermally stable.
