Método para manipular, isolar, detectar ou amplificar um ácido nucleico alvo em uma amostra por hibridização com um conjugado de oligonucleotídeo-oligocátion.

摘要

The invention relates a method for manipulating, isolating, detecting or amplifying a target nucleic acid in a sample by hybridization with an oligonucleotide-oligocation molecule, comprising allowing said nucleic acid to react with an oligonucleotide- oligocation of structure I
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒA i B j H€ƒ€ƒ€ƒ€ƒ€ƒ(I)
wherein
. A i is an i-mer oligonucleotide residue, with i = 3 to 50, where nucleotide A is an oligomer with naturally or non naturally occurring nucleobases and/or pentafuranosyl groups and/or native phosphodiester bonds, optionally comprising a marker group
. B j is a j-mer organic oligocation moiety, with j = 1 to 50, where B is - HPO 3 -R 1 -CH(R 2 X)-R 3 -O-, where R 1 is lower alkylene, R 2 and R 3 , identical or different, are lower alkylene and X is putrescine, spermidine or spermine residue.
