PAC-dA Phosphoramidite, standard grade, serum vial bottle (Thermo Scientific™)

PAC-dA CEP is a phosphoramidite containing 5' DMT and the nucleoside deoxyadenosine (dA) with Phenoxyacetyl (PAC) base protection, for use in oligonucleotide synthesis. The UltraMILD monomers - phenoxyacetyl (PAC)-dA, acetyl (Ac)-dC, and iso-propyl-phenoxyacetyl (iPr-PAC)-dG - were developed to alleviate the problem of modifiers and labels not withstanding prolonged exposure to strongly alkaline deprotection conditions. Cleavage and deprotection can be achieved in 4 hours at room temperature with 0.05M potassium carbonate in methanol. 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 ABI Systems|AKTA Systems of oligonucleotide synthesizers.
