Product information

While many of our fluorous products focus on the purification of oligonucleotides,(1) fluorous tags have other potential applications in nucleic acid chemistry. 3'-Fluorous modifier CPG is useful for placing a permanent fluorous tag at the 3'-terminus of an oligonucleotide. In addition to providing a purification handle, fluorous modifications enable applications where fluorophilicity or high hydrophobicity are desired. For example, the presence of a fluorous tag in an oligonucleotide may allow its immobilization onto fluorous-coated glass slides.(2) Alternatively, placing fluorous monomers at strategic sites in an oligonucleotide may allow intra- or intermolecular fluorous-fluorous interactions, enhancing the attraction between various regions of an oligonucleotide.

Soc. 2005, 127, 13162-13163. (b) Spring and co-workers showed that fluorous-tagged small molecules could be immobilized on fluorous modified a glass surface and used to facilitate detection of protein-ligand binding interactions; see: Nicholson, R. L.; Ladlow, M. L.; Spring, D. R. Chem. Commun. 2007, 3906-3908. (c) Schreiber and co-workers employed fluorous-immobilized small-molecule arrays to screen for histone deacylase inhibitors; see: Vegas, A. J.; Bradner, J. E.; Tang, W.; McPherson, O. M.; Greenberg, E. F.; Koehler, A. N.; Schreiber, S. L. Angew. Chem. Int. Ed. 2007, 46, 7960-7964.
