摘要:
The present invention describes a method for producing a target substance using a microorganism comprising culturing an Escherichia bacterium in a medium to produce and accumulate the target substance in the medium or the bacterium, and collecting the target substance. More specifically, the bacterium of the present invention can be a strain in which the fis gene on bacterial chromosome is disrupted so that the FIS protein does not function normally in the bacterium.
摘要:
Novel hybridisation assay probes and mixtures of such probes for detecting a target sequence of one or mycobacteria optionally present in a sample. The probes may suitable be directed to target sequences of mycobacterial rDNA, precursor rRNA, or rRNA, said probes being capable of forming detectable hybrids. The probes are in particular directed to mycobacterial rDNA, to precursor rRNA, or to 23S, 16S or 5S rRNA The probes are useful for detecting the organisms in test samples such as sputum, laryngeal swabs, gastric lavage, bronchial washings, biopsies, aspirates, expectorates, body fluids (spinal, pleural, pericardial, synovial, blood, pus, bone marrow), urine, tissue sections as well as food samples, soil, air and water samples, and cultures thereof.
摘要:
A thermal cycling method and device is disclosed. The device comprises a sample chamber whose temperature can be rapidly and accurately modulated over a range of temperatures needed to carry out a number of biological procedures, such a DNA polymerase chain reaction. Biological samples are placed in glass micro capillary tubes and then located inside the sample chamber. A programmable controller regulates the temperature of the sample inside the sample chamber. Once a heating cycle is completed, the controller opens a door to the chamber for venting hot air out and cool ambient air is moved in. Temperature versus time profiles corresponding to optimum denaturation, annealing and elongation temperatures for amplification of DNA are achieved by the present invention.
摘要:
The present invention provides methods relating to chemotherapeutic treatment of a cell proliferative disorder. In particular, a method is provided for predicting the clinical response to certain types of chemotherapeutic agents. Alkylating agents, used for the treatment of certain types of tumors including tumors of the nervous system and lymph system, are efficacious agents when the damage they do to tumor cell DNA is not repaired by cellular DNA repair mechanisms. The present invention provides a method for determining the activity of a gene encoding a DNA repair enzyme, thus providing a prediction of the clinical response to alkylating agents.
摘要:
The present invention relates to PNA derivatives which carry, at the N terminus of the PNA backbone, a phosphoryl radical. The phosphoryl radical can be, for example, a phosphate radical, or a substituted phosphoryl radical, with substituted phosphoryl derivatives carrying, where appropriate, one or more labeling groups, groups for crosslinking, groups which promote intracellular uptake, or groups which increase the binding affinity of the PNA derivative for nucleic acids. The invention furthermore relates to a process for preparing the abovementioned PNA derivatives and to their use as pharmaceuticals and diagnostic agents.
摘要:
The invention is directed to methods for detecting, monitoring and/or diagnosing aberrant cellular proliferation, and disorders associated therewith, such as cancer, and/or infection by microorganisms. The detection, monitoring and/or diagnosis comprises contacting a compound of the invention with a cell or fluid sample. Compound binding confirms the presence of an abnormal cell or a protein associated with an abnormal cell or infection by one or more microorganisms, and/or disorders associated with infection by one or more microorganisms.
摘要:
An array of autoantibodies is quantitated in a patient sample and analyzed toward a diagnosis of systemic autoimmune diseases. The analysis uses any of various known pattern recognition techniques, for example k-nearest neighbor analysis, to compare the array of quantitation data to sets of data previously obtained from subjects having known systemic autoimmune diseases, thereby determining the particular disease(s) that the patient is suffering from as well as the degree of confidence or likelihood of accuracy of the determination. The method is effective in identifying a single disease and also in identifying two or more diseases simultaneously present. The method is readily susceptible to automated data processing, eliminating much of the human judgment and error that were previously entailed in diagnosing these diseases.
摘要:
The present invention is directed to detection and measurement of gene transcripts and their equivalent nucleic acid products in blood. Specifically provided is analysis performed on a drop of blood for detecting, diagnosing and monitoring diseases using gene-specific and/or tissue-specific primers. The present invention also describes methods by which delineation of the sequence and/or quantitation of the expression levels of disease-specific genes allows for an immediate and accurate diagnostic/prognostic test for disease or to assess the effect of a particular treatment regimen.
摘要:
The present invention relates to a method for screening a collection of nucleic acid molecules for a desired property of the nucleic acid or of a (poly)peptide encoded thereof, comprising the steps (a) automated picking of the cell collection containing the collection of nucleic acid molecules with a first robot; (b) automated lysis of the cells with a second robot; (c) automated separation of the cell DNA from the cell debris with a second robot; (d) optionally automated separation of endotoxins from the DNA with the second robot if the cells are bacteria; (e) automated transfection of the cells with the DNA obtained in step (c) or, if the cells are bacteria, with the DNA obtained in step (d) with a third robot; and (f) automated screening for the desired property with a fourth robot. Moreover, the invention relates to methods for the enhancement of the binding properties of the (poly)peptide identified by the of the screening method of the invention or encoded by the DNA identified and isolated and a method for the production of a pharmaceutical composition on the basis of (poly)peptides which can be obtained with the method of the invention and moreover the formulation of the substance obtained with a pharmaceutically acceptable carrier or dilutent.
摘要:
The present invention relates to AUR1 and/or AUR2 polypeptides, nucleic acids encoding such polypeptides, cells, tissues and animals containing such nucleic acids, antibodies to such polypeptides, assays utilizing such polypeptides, and methods relating to all of the foregoing. Methods for treatment, diagnosis, and screening are provided for AUR1 and/or AUR2 related diseases or conditions characterized by an abnormal interaction between a AUR1 and/or AUR2 polypeptide and a AUR1 and/or AUR2 binding partner.
