Abstract: Novel CE-phosphoramidites and CPG reagents have been synthesized from a serinol backbone. These reagents are useful to introduce functional groups or directly label oligonucleotides. The versatile serinol scaffold allows for labeling at any position (5? or 3? termini, or any internal position) during automated DNA synthesis. Multiple labels or functional groups can be achieved by repetitive coupling cycles. Optimal spacer arms and protected label moieties have been specially designed. Further, the natural 3-carbon atom internucleotide phosphate distance is retained when inserted internally.

Abstract: Universal supports for oligonucleotide synthesis include a support material represented by the following formula: In this formula, substituent A is selected from H, alkyl, aryl, or a polymeric or silica base material; substituent B is selected from acyl, aroyl, or a polymeric or silica base material; and substituent C is selected from a dimethoxytrityl group or a protecting group removable under acidic or neutral conditions. For the supports, one of substituents A or B constitutes the polymeric or silica base material. In use, an oligonucleotide is attached to the support at substituent C.

Abstract: A fluorescent nitrogenous base and nucleosides including the fluorescent nitrogenous base are provided. Nucleosides including the fluorescent nitrogenous base are capable of Watson-Crick base pairing with naturally occurring nucleosides. The nucleosides including the fluorescent nitrogenous base have many uses including but not limited to use in probes, in the synthesis of nucleic acids, and in investigating nucleic acid interactions with other nucleic acids and/or with proteins.

Abstract: Phosphoramidite building blocks according to the following formula 1 are used for phosphorylating oligonucleotides, preferably at the 5'- or 3'-terminus. The building blocks include phosphoramidite compounds according to formula 1: ##STR1## wherein DMTr is a 4,4'-dimethoxytrityl group; R.sub.1 is an electron withdrawing group; R.sub.2 is an electron withdrawing group which may be the same or different from the R.sub.1 group; R.sub.3 is an alkyl group; and R.sub.4 is an alkyl group which may be the same or different from the R.sub.3 group. Preferred electron withdrawing groups include --CO.sub.2 Et groups, --CO.sub.2 Me groups, --CN groups, --CON(Me).sub.2 groups, and --CONHMe groups, wherein Et represents an ethyl group and Me represents a methyl group. One preferred alkyl group is an isopropyl group.
