2'-OMe-U CEP is a phosphoramidite containing 5' DMT and the nucleoside uridine (U) 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 20-mL amber bottle with a serum vial neck style, which is compatible with most Applied Biosystems synthesizers and AKTA synthesizers.
