标题:Method and apparatus for monitoring the automated synthesis of peptides

摘要:A method for monitoring a solid-phase peptide synthesis for free amino ends of unreacted peptide chains, the monitoring occurring at the end of each addition of a blocked amino acid to the peptide chains which are anchored to the solid phase. The method includes reacting the solid phase with a monitoring agent that forms a covalent bond with unblocked amino groups. The solid phase is then washed to remove the unreacted monitoring agent. A cleaving reagent is then used to selectively remove the covalently bound monitoring reagent from the ends of the unblocked peptide chains, while leaving the blocked chains intact. The amount of monitoring agent thus removed is then quantitatively measured to determine what proportion of the initial peptide chains failed to react with the blocked amino acid. Preferred monitoring agents for use in this process include trityl (triphenylmethyl) -based groups, and particularly preferred agents are trityl, monomethoxytrityl, dimethoxytrityl, and trimethoxytrityl chlorides.

标题 :Single-stranded labelled oligonucleotides of preselected sequences
发明人：RUTH JERRY L
权利人:MOLECULAR BIOSYSTEMS INC
摘要:Substantially pure single-stranded oligonucleotides having a preselected sequence of not more than about 200 nucleotides, at least one of which is at a preselected position in the sequence and includes a base with a covalently attached linker arm containing or capable of binding at least one reporter group or solid support. A process for the chemical synthesis of the substantially pure single-stranded oligonucleotide and modified nucleosides useful in such synthesis are provided.

摘要:A method of preparing an immobilized oligonucleotide having a free 3′-end comprises the steps of: i) preparing an oligonucleotide attached in a first position to a solid support via its 3′-end and having a free 5′-end; ii) binding said oligonucleotide in a second position remote from the 3′-end to the solid support; and iii) selectively releasing the 3′-end of the oligonucleotide from the solid support to obta the oligonucleotide attached to the support in said second position in a reversed orientation with a free 3′-end.
