    摘要: Intermediates and methods for forming passivated surfaces on oxide layers and articles produced thereby are described. Hydroxyl or hydroxide groups on the oxide surfaces are reacted with a metal reagent of the formula Y(L-Pol)m, where Y is a transition metal, magnesium or aluminum, L is oxygen, sulfur, selenium or an amine, and “Pol” represents a passivating agent such as a polyethylene glycol, a hydrocarbon, or a fluorocarbon. The resulting modified surface can be further reacted with a passivating agent having a phosphate functional group or a polyvalent reagent comprising a passivating moiety and a plurality of functional groups that are reactive with or that form complexes with Y. The passivating agent can also include a functional group such as biotin to provide surfaces with a desired functionality. The passivated surfaces exhibit minimal binding to bio-molecules and can be used in single-molecule detection schemes.

    摘要: The present invention provides a novel class of fluorescent cyanine dye compounds that are modified at one of the hetercyclic ring nitrogen atoms with a mobility-modifying moiety that permits the electrophoretic mobilities of polynucleotides labeled with the mobility-modifying cyanine dyes to be adjusted or tuned in a predictable fashion while retaining enzymatic activity. The ability to predictably tune the relative electrophoretic mobilities of the dyes permits the creation of sets of mobility-matched fluorescent dyes of a variety of structures for a variety of applications, including fluorescence-based 4-color nucleic acid sequencing reactions.
