    • Compositions and methods for covalently immobilizing an oligonucleotide onto a polymer-coated solid support or similar structure are provided. Specifically, the polymer-coated support, such as a bead, possesses a large number of activatable moieties, preferably primary and secondary amines. An oligonucleotide is activated with a monofunctional or multifunctional reagent, preferably the homotrifunctional reagent cyanuric chloride. The resultant covalently immobilized oligonucleotides on the support serve as nucleic acid probes, and hybridization assays can be conducted wherein specific target nucleic acids are detected in complex biological samples. The beads or similar structures can be employed free in solution, such as in a microtiter well format; in a flow-through format, such as in a column; or in a dipstick. Additionally, dichlorotriazine oligonucleotides and processes for activating oligonucleotides by treatment with cyanuric chloride and derivatives are included in the present invention.
