    • Image acquisition and analysis systems and methods are provided. A ray-based approach may be used to process images for cell-based assays. Such cell-based assays may be used to evaluate drugs or other compounds or to perform other biological studies. A scanning laser microscope or other equipment may be used to gather image data from fluorescently-marked cells (42) or other suitable specimens. The rays (40) are radially-oriented with respect to the cell nuclei (44). Seed points (48) within the nuclei (44) may be identified. The rays (40) may extend outward from the seed points (48) or other suitable ray origins until the rays (40) are terminated according to ray termination criteria. The intensity of the image data that is associated with each of the rays (40) may be analyzed to generate various parameters. For example, a peak intensity of the image data along each ray may be identified. Statistical calculations may be performed.

    • A method for detecting a mutation in a target nucleic acid sequence that comprises attaching oligonucleotide primers to a substrate, wherein the oligonucleotide primers have a sequence that is complementary to the target nucleic acid sequence, and wherein the oligonucleotide primers are grouped according to the identity of the first base which would be expected to be added to the primer through the process of primer extension; hybridizing to the oligonucleotide primers a sample nucleic acid sequence which possibly contains a mutation; extending each oligonucleotide primer by one base using a reaction mixture comprising labeled ddNTPs; and detecting a mutation in the sample nucleic acid sequence by detecting the presence of a labeled ddNTP which does not correspond to the identity of the base expected to be added to the primer through the process of primer extension. Mutations may be detected in mRNA or DNA. The labeled ddNTPs may be labeled with a fluorescent dye, a chemiluminescent reagent, a radioactive label, or an electrically conductive tag. A nucleic acid array and a kit for detecting genetic mutations are also disclosed. The instant disclosure also pertains to a method for detecting a mutation in a target nucleic acid sequence that comprises identifying the base expected to be added to a primer located at a particular coordinate on an oligonucleotide array as expected from the target nucleic acid sequence; identifying the base actually added to the primer located at the particular coordinate on the oligonucleotide array through the process of primer extension; comparing the base actually added to the primer at the particular coordinate with the base expected to be added to the primer at the particular coordinate; and reporting those instances where the bases are not the same, in order to identify a mutation.

    • This invention provides methods for nucleic acid analysis. A closed complex of nucleic acid template, nucleotide and polymerase can be formed during polymerase reaction, absent divalent metal ion. This is used to trap the labeled nucleotide complementary to the next template nucleotide in the closed complex. Detection of the label allows determination of the identity of this next correct nucleotide. Identification can be either in place, as part of the complex, or as the dye is eluted from the complex when the reaction cycle is completed by the addition of divalent metal ion. In this way, sequential nucleotides of a DNA can be identified, effectively determining the DNA sequence. This method can be applied to nucleic acid single molecules or to collections of identical or nearly identical sequence such as PCR products or clones. Multiple templates can be sequenced in parallel, particularly if they are immobilized on a solid support.

    • The present invention relates to improved methods of detecting a target using a labeled substrate or substrate analog. The methods comprise reacting the substrate or substrate analog in an enzyme-catalyzed reaction which produces a labeled moiety with independently detectable signal only when such substrate or substrate analog reacts. The present invention, in particular, describes methods of detecting a nucleic acid in a sample, based on the use of terminal-phosphate-labeled nucleotides as substrate for nucleic acid polymerases. The methods provided by this invention utilize a nucleoside polyphosphate, dideoxynucleoside polyphosphate, or deoxynucleoside polyphosphate analogue which has a colorimetric dye, chemiluminescent, or fluorescent moiety, a mass tag or an electrochemical tag attached to the terminal-phosphate. When a nucleic acid polymerase uses this analogue as a substrate, an enzyme-activatable label would be present on the inorganic polyphosphate by-product of phosphoryl transfer. Cleavage of the polyphosphate product of phosphoryl transfer via phosphatase leads to a detectable change in the label attached thereon. When the polymerase assay is performed in the presence of a phosphatase, there is provided a convenient method for real-time monitoring of DNA or RNA synthesis and detection of a target nucleic acid.
