Abstract
Methods and systems for monitoring a plurality of different optical signals from a single source of such signals, where each such different optical signal is spatially separated from other such signals and directed to different detectors or locations upon a single detector, which direction is generally accomplished through the use of a small number of optical components and/or manipulations.

41. A method of identifying nucleotides in a nucleic acid sequence, comprising:
-
providing a plurality of polymerization complexes within a plurality of confined reaction environments, wherein each complex comprises a polymerase enzyme, and a template nucleic acid; contacting the plurality of complexes with a plurality of types of nucleotide analogs labeled with distinguishable fluorescent labels under conditions suitable for polymerization; transmitting fluorescent signals associated with incorporation of a nucleotide analog to a detector, wherein location of the fluorescent signals on the detector is indicative of an individual confined reaction environment and a type of nucleotide incorporated; identifying a nucleotide in a nucleic acid sequence based upon the type of nucleotide incorporated and the confined reaction environment. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48)

49. A method of identifying nucleotides incorporated in polymerase mediated, template dependent nucleic acid synthesis reactions comprising:
-
providing a plurality template nucleic acid/polymerase complexes on a substrate; contacting the plurality of complexes with a plurality of nucleotide analogs having spectrally distinct fluorescent labels, wherein incorporation of nucleotides produces characteristic incorporation signals; directing incorporation signals to a single detector, wherein a location of a signal on the detector is indicative of a complex incorporating the nucleotide and a type of nucleotide incorporated; and identifying the nucleotide incorporated into a template mediated nucleic acid synthesis reaction from the location of the signal on the detector. - View Dependent Claims (50, 51, 52, 53)

54. A method of analyzing a reaction, comprising:
-
providing a first reactant immobilized on a substrate; contacting the first reactant with a second reactant and a third reactant, each bearing a spectrally distinct label; directing signals from the spectrally distinct labels that are characteristic of interaction of the first reactant with one of the second and third reactants to a location on a first detector, wherein the location on the detector is indicative of the first reactant location on the substrate and the second or third reactant with which the first reactant interacted; identifying the first reactant and the second or third reactant with which the first reactant interacted. - View Dependent Claims (55, 56, 57, 58, 59, 60)
