Thermo Scientific™ 2'-OMe-iBu-G Phosphoramidite, standard grade, 28-400 finish bottle

2'-OMe-iBu-G CEP is a phosphoramidite containing 5' DMT and the nucleoside guanosine (G) with 2'-O-methyl protection, for use in oligonucleotide synthesis. Located in the ideal oligo position, 2'-O-methyl (OMe) oligo modifications display nuclease resistance, fewer off-target effects, and slightly increased hybridization affinities. These phosphoramidites are commonly used for oligos designed for antisense, siRNA, aptamer, or gRNA-based research. The 'standard grade' marking denotes a baseline level of purity verified with analytical methods, and proven to be suitable for most oligo synthesis requirements. This product is supplied in a 30-mL amber bottle with a 28-400 finish neck style, which is compatible with most MerMade synthesizers.
