摘要:
An oligonucleotide-solid phase conjugate, wherein the solid phase is thiophilic and the oligonucleotide comprises at least one thiooxonucleobase according to Formula I, wherein X is CH or N, R1 is H or NH2, --- indicates a covalent bond, and said oligonucleotide is bound to said solid phase via the sulfur atom of said thiooxonucleotide. Also disclosed are methods for producing such conjugate as well as various uses for such oligonucleotide metal conjugate.
摘要:
Within oligonucleotides 2-azapurine and especially 2-azaadenine bases form specifically base pairs with guanine. This base pair is of analogous stability as an adenine-thymine but less stable than a guanine-cytosine base pair. Therefore, the incorporation of 2-azaadenine residues into oligonucleotides instead of cytosine leads specifically to hybridization complexes with nucleic acids with homogenous stability. This is useful for the adaptation of the stabilities of different oligonucleotide sequences in all kinds of hybridization techniques, for example in oligomer chip technology.
