摘要: Enzymatic synthesis of short (10–22 nt) base-modified oligonucleotides (ONs) was developed by nicking enzyme amplification reaction (NEAR) using Vent(exo-) polymerase, Nt.BstNBI endonuclease, and a modified deoxyribonucleoside triphosphate (dNTP) derivative. The scope limitations the methodology in terms different nucleobases, length, sequences, modifications has been thoroughly studied. including isolation ONs scaled up to nanomolar amounts were successfully used as primers primer extension PCR. Two simple efficient methods for fluorescent labeling PCR products developed, based either on direct or NEAR ethynylated primers, PCR, final click with azides.
