    • Methods for the construction, labelling and subsequent purification of nucleic acid probes containing primary amines with acridinium esters 4-(2-succinimidyloxycarbonyl-ethyl)phenyl-10-methylacridinium-9-carboxylate fluorosulfonate). The method for attaching acridinium esters to probes uses high (0.1 to 50 mM) acridinium ester concentrations achieved using organic solvent in concentrations of 20% to 80% by volume, and may be carried out either in solution, or with one or the other of the acridinium ester or the probe suspended in solution. Purification (the separation of labelled probe from unlabelled probe and free label) involves (1) first removing most of the free acridinium ester label from probe using rapid separation techniques, then (2) removing substantially all remaining free label from the probe and separating labelled probe from unlabelled probe, involves specific applications of ion exchange, reverse phase or hydroxyapatite HPLC.

    • The present invention provides methods for immobilizing target nucleic acids on a solid support utilizing combinatorial capture probe pairs. These pairs contain first and second capture oligonucleotides that each comprise a target binding region, a capture region and a stem region positioned between the target binding and capture regions. The target binding regions comprise nucleic acid sequences that allow them to hybridize to adjacent regions on the target nucleic acid. The stem regions have nucleic acid sequences that are complementary to each other and the capture regions each comprise a sequence that when positioned adjacent to one another produce a combined nucleic acid sequence that is complementary to a portion of an oligonucleotide bound to a solid support. When the first and second capture oligonucleotides are annealed to the target nucleic acid, the stem regions are brought together allowing them to hybridize, which in turn brings the capture regions together to produce a combined nucleic acid sequence. This combined nucleic acid sequence is then able to hybridize to the oligonucleotide bound to the solid support thereby immobilizing the target nucleic acid.

    • A versatile reagent with a non-nucleotide monomeric unit having a ligand, and first and second coupling groups which are linked to the non-nucleotide monomeric unit. The ligand can be either a chemical moiety, such as a label or intercalator, or a linking arm which can be linked to such a moiety. Such reagent permits preparation of versatile nucleotide/non-nucleotide polymers, having any desired sequence of nucleotide and non-nucleotide monomeric units, each of the latter of which bear a desired ligand. These polymers can for example, be used as probes which can exhibit enhanced sensitivity and/or which are capable of detecting a genus of nucleotides each species of which has a common target nucleotide sequence of interest bridged by different sequences not of interest.

    • A versatile polymeric support system for the synthesis of oligonucleotides is provided featuring a universal primer which allows chain elongation, in either the 3' or 5' direction, with any currently available DNA or RNA synthesis method, by a process which utilizes oxidatively cleaved primers to facilitate chain elongation and release. The support system is capable of withstanding mildly basic and acidic reaction conditions, while still permitting a convenient and quantitative release, either before or after removal of protecting groups from reactive groups, of synthesized oligonucleotides from a single polymeric support. Removal of the protecting groups before cleavage of the oligomer from the support permits the use of the immobilized oligomer as an affinity hybridization support for both isolating and detecting complementary polynucleic acids.
