1. A method for separating oligonucleotides, said method comprising:
- a) providing a plurality of oligonucleotides, said plurality of oligonucleotides comprising at least one bifunctional oligonucleotide and at least one non-bifunctional oligonucleotide, wherein each said at least one bifunctional oligonucleotide comprises a first separation tag attached to a first end of said at least one bifunctional oligonucleotide and a second separation tag attached to a second end of said at least one bifunctional oligonucleotide, and wherein cleavage of said first or said second separation tags yields an oligonucleotide having a 3′
hydroxyl moiety;
b) contacting said plurality of oligonucleotides with a separation medium under conditions effective for adhering said at least one bifunctional oligonucleotide to said separation medium; and
c) selectively eluting at least one non-bifunctional oligonucleotide.

27. A method for separating oligonucleotides, said method comprising:
-
a) providing a plurality of oligonucleotides, wherein said plurality of oligonucleotides comprises at least one bifunctional oligonucleotide and at least one non-bifunctional oligonucleotide, and wherein each said at least one bifunctional oligonucleotide comprises a first separation tag attached to a first end of said at least one bifunctional oligonucleotide and a second separation tag attached to a second end of said at least one bifunctional oligonucleotide, and wherein cleavage of said first or said second separation tags yields an oligonucleotide having a 3′
hydroxyl moiety;
b) contacting said plurality of oligonucleotides with a separation medium under conditions effective for adhering said at least one bifunctional oligonucleotide to said separation medium;
c) eluting non-bifunctional oligonucleotides lacking said first separation tag without eluting said bifunctional oligonucleotides;
d) cleaving said first separation tag from the oligonucleotides retained on the separation medium; and
e) eluting non-bifunctional oligonucleotides lacking said second separation function. - View Dependent Claims (28, 29)

30. A composition comprising:
-
a) a plurality of oligonucleotides, each said oligonucleotide comprising a first separation tag attached to a first end of said oligonucleotide and a second separation tag attached to a second end of said oligonucleotide, wherein cleavage of said first or said separation tags yields an oligonucleotide having a 3′
hydroxyl moiety; and
b) a separation medium, said plurality of oligonucleotides adhering to said separation medium. - View Dependent Claims (31)
