  • Patent number: 8735085
    Abstract: One aspect of the invention provides a method of diagnosing a disease condition, comprising measuring presence or amount of a targeted protein or a degradation product of said protein in a collected biological sample as a marker for the disease condition. The targeted protein or degradation product is selected for measurement based on a prior identification of a measurable half-life at a predetermined time period, including the time at which said method is conducted, and correlating said measuring with the presence or absence of the disease condition. The targeted protein or degradation product may be identified by selecting a protein known or suspected to be a diagnostic marker for the disease condition, analyzing degradation of the protein in the collected biological sample, and selecting a protein or degradation product that exhibits a measurable half-life at a predetermined period of time.

  • Patent number: 7361489
    Abstract: The present invention relates to assays and kits for carrying out said assays for the rapid, automated detection of infectious pathogenic agents and normal and abnormal genes. The present invention further relates to methods for general amplification of genomic DNA and total mRNAs and for analyzing differential mRNA expression using the amplification methods disclosed herein.

  • Publication number: 20080017577
    Abstract: The fluid sample collection device is adapted to collect and separate a fluid sample into constituent parts such as separating plasma or serum from a blood sample. The device includes an evacuated outer container and an inner container. The outer container has a first open end and a second closed end. A pierceable closure closes the first open end thereby defining a first interior chamber. The inner container is contained within the outer container and separates the first interior chamber into an upper chamber portion and lower chamber portion in fluid communication. The inner container defines a second interior chamber separated from the lower chamber portion through a porous membrane. A port is provided for placing the second interior chamber in fluid communication with the first interior chamber. Another aspect of the device relates to a method of using the device to separate plasma or serum from a blood sample.

  • Publication number: 20050037353
    Abstract: The present invention relates to methods for identification and quantification of proteins expressed within a cell. The methods of the invention involve the separation of proteins based on their physical properties such as, for example, net charge, molecular weight, or immunoreactivity, followed by detection of said proteins using a number of different techniques including (i) ramification-extension amplification method (RAM); (ii) hybridization signal amplification method (HSAM); and (iii) detection with nanodots. The methods of the invention will have a variety of different uses including, but not limited to, uses for screening, for diagnosis and prognosis of disease. The methods of the invention are especially useful for identification of proteins that are not easily identified due to the small size of the protein, low concentration of the protein, or failure to separate proteins due to similar physical properties.
