Patent ID: 8183355

Claim:
Molecule of formula (XIV): wherein X is selected from N, O, S, an alcane di-yl comprising 1 to 12 carbon atoms; m is an integer, m≧1 L is a linker selected from the following list: alcane poly-yl functions with 1 to 12 carbon atoms, linear branched or cyclic possibly interrupted by one or several oxygen (—O—), nitrogen (—NH—, —N═) or sulphur (—S—) bridges or phosphodiester [—O—(O − )P(═O)—O—] bridges; x is an integer, 30≧x≧1 x′ is an integer, 30≧x′≧1 D is a linker between X and the alkyne group(s) wherein according to the value of x, D's valency is 2 or more and D is selected from alcane poly-yl groups comprising 1 to 36 carbon atoms, possibly interrupted by one or several oxygen (—O—), nitrogen (—NH—, —N═) or sulphur (—S—) bridges or phosphodiester [—O—(O − )P(═O)—O—] bridges; according to the choice of X and D, y is 0, 1 or 2; D′ is a linker between L and the alkyne group(s) wherein according to the value of x′, D′'s valency is 2 or more, and D′ is selected from alcane poly-yl groups comprising 1 to 36 carbon atoms, possibly interrupted by one or several oxygen (—O—), nitrogen (—NH—, —N═) or sulphur (—S—) bridges or phosphodiester [—O—(O − )P(═O)—O—] bridges; z and z′ are integers, z and z′≧0, at least one of z and z′ is ≧1; B is selected from H, a solid support or a tag.
