Abstract: The present invention relates generally to nucleobase polymer functionalizing reagents, to mobility-modified sequence-specific nucleobase polymers, to compositions comprising a plurality of mobility-modified sequence-specific nucleobase polymers, and to the use of such polymers and compositions in a variety of assays, such as, for example, for the detection of a plurality of selected nucleotide sequences within one or more target nucleic acids. The mobility-modifying polymers of the present invention include phosphoramidite reagents which can be joined to other mobility-modifying monomers and to sequence-specific oligonucleobase polymers via uncharged phosphate triester linkages. Addition of the mobility-modifying phosphoramidite reagents of the present invention to oligonucleobase polymers results in unexpectedly large effects the mobility of those modified oligonucleobase polymers, especially upon capillary electrophoresis in non-sieving media.

Abstract: This invention relates to attachment chemistries for binding macromolecules to a substrate surface or to other conjugation targets. More particularly, this invention relates to attachment chemistries involving branched or linear structures having one or more hydrazide attachment moieties for binding the macromolecules to a substrate surface, or for other conjugation reactions. Novel modifying reagents are provided for the introduction of protected hydrazide attachment moieties or precursor forms of such hydrazides to the macromolecule, either as a single hydrazide or as multiple hydrazides.

Abstract: A scalable process for purification of phosphorodiamidite includes steps of solubilizing a crude phosphorodiamidite in an apolar organic solvent, contacting the non-polar organic solvent with a polar phase comprising a polar organic solvent to remove impurities from the solubilized phosphorodiamidite, and removing the non-polar organic solvent from the phosphorodiamidite.

Abstract: Membrane-permeant phosphoinositides, including phosphatidylinositol phosphate esters, are described. A membrane-permeant phosphoinositide includes groups that neutralize the charges of the phosphate moieties of the phosphoinositide. A cell can be treated with the membrane-permeant phosphoinositide, which is then absorbed into the cell. The neutralizing groups can be removed intracellularly to afford the charged phosphoinositide.
