Thermo Fisher, 27-1601-12, 2'-Fluoro-Bz-A Phosphoramidite, standard grade, 28-400 finish bottle

Quantity: 0.5 g
Unit Size: Each
2'-Fluoro-Bz-A CEP is a phosphoramidite containing 5' DMT and the nucleoside adenosine (A) with 2'-Fluoro protection, for use in oligonucleotide synthesis. Located in the ideal oligo position, the highly electronegative fluorine (2'-Fluoro) modification adopts a more thermodynamically stable A-form helix on hybridization to its target. Showing improved affinity and some nuclease resistance (compared to 2'-OH), the 2'-F modification has been proven useful in antisense, siRNA, and aptamer applications. 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.
