1. An array comprising:

  • (A) a support surface; and

    (B) a plurality of modified oligonucleotide compositions, each composition comprising a plurality of oligonucleotides stably associated with a distinct area of the support surface, wherein the oligonucleotides of each composition are characterized by;

    (1) independently having a length of from about 20 to about 300 nucleotides;

    (2) having internucleotide linkages selected from the group consisting of 2′

    -O-alkyl, 2′

    -O-alkyl-n(O-alkyl), combinations thereof;

    (3) having a binding affinity to a complementary sequence greater than the corresponding binding affinity of a non-modified oligonucleotide having the same sequence; and

    (4) having a pH stability of at least one hour at 37°

    C. at a pH in a range of about 0.5 to 6.
