ABSTRACT:
Methods for covalent attachment of oligonucleotides to solid supports such that substantially all of the oligonucleotides are attached via their 5'-ends are provided. The solid supports with attached oligonucleotides are produced. Thiol-oligonucleotides are attached to bromoacetyl-derivatized polyacrylamide supports, or conversely, bromoacetyl-oligonucleotides are immobilized on thiol-polyacrylamide supports. In a further aspect, bromoacetyl-derivatized oligonucleotides, and polyacrylamide supports with linked oligonucleotides produced by coupling bromoacetyl-derivatized oligonucleotides with thiol-derivatized polyacrylamide solid supports or by coupling thiol-derivatized oligonucleotides with bromoacetyl-derivatized polyacrylamide supports as well as methods for capture of nucleic acids by oligonucleotides attached to polyacrylamide solid supports, either by direct capture or in sandwich hybridization formats are provided.
