An apparatus and method are provided for creating an image of a microarray. The apparatus includes at least one light source configured to direct light toward the microarray. The apparatus includes an excitation filter configured to filter the light into a first frequency band towards dichromatic mirror. The dichromatic mirror reflects light onto the microarray causing the microarray to emit electromagnetic energy. The apparatus includes emission filter configured to filter the electromagnetic energy within a second frequency band. The apparatus further includes an imaging unit having a charged coupled device (CCD), the CCD having an imaging surface masked by a pinhole blind such that when the pinhole blind receives electromagnetic energy from the emission filter, an image is created of the entire micro array.

摘要:
The present invention provides a specific set of gene expression markers from peripheral blood leukocytes that are indicative of a host response to exposure, response, and recovery infectious pathogen infections. The present invention further provides methods for identifying the specific set of gene expression markers, methods of monitoring disease progression and treatment of infectious pathogen infections, methods of prognosing the onset of an infectious pathogen infection, and methods of diagnosing an infectious pathogen infection and identifying the pathogen involved.
摘要:
A method and apparatus for the processing of DNA sequence image data in real time is implemented using a series of linked neural network processors. As raw image data is received from a sequencing machine, it is buffered and then separately transformed in real time in the processors to enhance the signals indicative of the unknown DNA sequence. A fourth processor receives the transformed data and determines and reports the sequence indicating events.
摘要:
A novel alteration of a viral DNA sequence, derived from a human adenovirus type 3 mutant (Ad3) designaed Ad3h15, provides a transcriptional control element which can be used to regulate expression of a selected gene in animal and human cells. The Ad3h15 control element blocks transcription of a controlled gene in the presence of the products of the Ad3 E1A gene, and amplifies transcription in the presence of type 5 (Ad5) adenovirus E1A gene products.
摘要:
The present invention relates to pathogen detection and identification by use of DNA resequencing microarrays. The present invention also provides resequencing microarray chips for differential diagnosis and serotyping of pathogens present in a biological sample. The present invention further provides methods of detecting the presence and identity of pathogens present in a biological sample.
摘要:
A method and system for automated nucleic acid sequence determination of a polynucleotide, wherein a nucleic acid sequencing ladder comprises signals corresponding to oligonucleotides formed from the polynucleotide, comprising the step of correlating, particularly in a trained neural network or a scatter plot, an intensity variable for each signal in the nucleic acid sequencing ladder with an informative variable for that signal, wherein the informative variable comprises information from at least two adjacent signals in the nucleic acid sequencing ladder, such that each signal in the nucleic acid sequencing ladder identified so as to determine the nucleic acid sequence corresponding to the polynucleotide. In particular, the relative separation between consecutive signals, the relative intensities between consecutive signals, and a pattern recognition factor, which incorporates a comparison of relative separations and intensities of at least two adjacent signals with pattern recognition templates, can be used as informative variables. Furthermore, this invention relates to a method and system for the on-the-fly resolution and extraction of information of signals contained in a digitized data stream involving calculation of the smoothed second derivative of a data point from the smoothed first derivative of the data point.
