  • Patent number: 6083695
    Abstract: A novel method of primer walking using octamer oligonucleotides to prime DNA sequencing reactions is described. Octamer sequencing is compatible with isotopic and fluorescent sequencing chemistry, reaction conditions are optimized such that the samples can be processed in parallel and the procedures are automated. This strategy is faster than the traditional primer walking sequencing strategy as the existence of a primer library allows immediate access to a primer for the next sequencing reaction, eliminating delays associated with designing and synthesizing gene specific primers. The octamer library is comprised of optimized sequencing primers, such that octamer sequencing yields results equivalent to or better than traditional primer walking.

  • Patent number: 6077665
    Abstract: A rapid assay for infection in immunodeficient patients such as neonates or immunocompromised patients (e.g. HIV or transplant patients) allows diagnosis at initial evaluation, such that antibiotic treatment and confinement to an intensive care unit can be avoided for uninfected patients. The assay can be used for detecting bacterial, viral, or fungal colonization of the blood stream, cerebrospinal fluid (CSF), or urinary tract. The method is particularly useful for sepsis diagnosis. Polymorphonuclear leukocyte (PMN, neutrophil) CD11b (Mac-1, CR3) levels are measured by flow cytometry or laser scanning microscopy in low volume (0.1 ml) whole blood samples. A dual-laser FACS identifies neutrophils by FITC-conjugated anti-CD15 fluorescent antibodies, and identifies surface neutrophil CD11b marked with PE-conjugated anti-CD11b antibodies. Spontaneous upregulation of CD11b is prevented by handling samples at 4.degree. C. or adding a stabilizing compound such as anti-CD14 antibody or adenosine to the samples.

  • Patent number: 6074822
    Abstract: A test method and test kit for determining a risk of diabetic complications based upon abnormal aldose reductase genetic material expression is described. Cells isolated from a patient which exhibit elevated levels of aldose reductase genetic material expression at pathophysiologic levels of glucose (about 20 mM) which can occur commonly in the cells of diabetic patients are evaluated based upon a level of expression of DNA or RNA in the cells with the glucose at the pathophysiologic level. The cells can be used to isolate DNA or RNA for a probe which detects the abnormal aldose reductase gene expression. The method can be used to determine when particular aldose reductase inhibitors can be effective for a particular patient.

  • Patent number: 6072039
    Abstract: A hybrid polypeptide is disclosed, comprising a polypeptide for attachment of a prosthetic group to avidin fused to at least one polypeptide of interest, and a method of making the same. The hybrid polypeptide is produced by recombinant DNA techniques, using a DNA expression vector composed of a DNA fragment coding for the polypeptide for attachment to avidin fused to DNA coding for one or more polypeptides of interest. The hybrid polypeptide may also contain linking amino acid sequences for cleavage of the polypeptide of interest from the polypeptide for attachment using an appropriate proteolytic or chemical reagent. The hybrid polypeptide is expressed in appropriate host cells transformed with the DNA expression vector encoding the hybrid polypeptide, and may be recovered from crude cell extracts in high yield and high purity using avidin affinity chromatography.

  • Patent number: 6069240
    Abstract: Disclosed are methods for detecting mammalian genes encoding proteins which can function in microorganisms, particularly yeast, to modify, complement, or suppress a genetic defect associated with an identifiable phenotypic alteration or characteristic in the microorganism. Disclosed also are mammalian DNA sequences cloned by the above method, as well as polypeptide products of the expression of the DNA sequences in procaryotic or eucaryotic host cells and antibody substances which are specifically immunoreactive with said expression products. More specifically, the present invention relates to methods for cloning mammalian genes which encode products which modify, complement or suppress a genetic defect in a biochemical pathway in which cAMP participates or in a biochemical pathway which is controlled, directly or indirectly, by a RAS-related protein, to products (RNA, proteins) encoded by the mammalian genes cloned in this manner, and to antibodies which can bind the encoded proteins.

  • Patent number: 6057099
    Abstract: A method for detecting the presence of an assayed nucleic acid sequence in a sample is an essentially two stage-procedure. As illustrated, in a first stage the sample is reacted in a manner which gives rise to the production of a triggering oligonucleotide where the sample contains the assayed sequence. In the second stage, the reaction product is incubated under appropriate conditions with an amplification system whereby, in the presence of triggering oligonucleotide, a large amount of a nucleic acid product is obtained. The detection of this product thus indicates the presence of the assayed sequence in the sample.
