产品概述 技术指标 订购信息 服务支持
详细描述:
化学合成的DNA如探针、引物和其它寡核苷酸具有广泛的应用,可用于PCR,基因组测序,SNP基因分型和基因合成等。 LGC Biosearch提供多种亚磷酰胺修饰的荧光报告染料和非荧光淬灭染料,可用于合成复杂的qPCR探针。 其专利的Black Hole Quencher®(BHQ®)染料亚磷酰胺能够有效淬灭所有荧光基团,因此从480nm到近红外可见光谱范围内发射荧光的任何报告染料都可以与其搭配使用。 CAL Fluor®和Quasar®荧光基团亚磷酰胺的发射光谱跨越可见光和近红外光谱,是多重实时qPCR的理想选择。 此外,LGC Biosearch还提供多种修饰如生物素、氨基、巯基、间臂以及其它常用荧光染料的亚磷酰胺。这些亚酰胺可用于直接掺入修饰的寡核苷酸中。 Oligonucleotides having a 5'-phosphate group are valuable tools for many molecular biology applications including gene construction, cloning, mutagensis, and ligation chain reaction. Several methods have been developed to allow for the 5' phosphorylation of synthetic oligonucleotides. The most common is through the use of a 5'Phosphate Amidite (2-O-4,4'-dimethoxytrityl-2'-oxydiethane sulfonyl)-(2-cyanoethyl)-(N,N-diisopropyl)-phosphoramidite (BNS-5010). Unfortunately, the DMT group cannot be left on for DMT-ON purification due to the elimination reaction of the DMT and sulfonyl ethyl group during normal ammonium hydroxide deprotection and cleavage. Phosphorylating Amidite II contains a DMT group that can be removed to determine the coupling efficiency of the amidite or it may be left on to allow for reverse phase cartridge purification. To determine the coupling efficiency, the DMT group is removed on the synthesizer. The side chain is eliminated, during ammonium hydroxide deprotection and cleavage, to yield a 5'Phosphate. For DMT-ON purification, the DMT group is removed with aqueous acid (3% TFA) and the side chain is eliminated after treatment with ammonium hydroxide.
