    • 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. The analyzing may include identifying degradation product (s) of the protein as a function of time, and half-life of the protein and the degradation product (s).

    • 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 mot limited to, uses for screening, for diagnosis and prognosis of disease. The method of the invention are especially useful for identification of proteins that are identified due to the size of the protein, low concentration of the protein, or failure to separate proteins due to similar physical properties.
    • 本发明涉及鉴定和定量细胞内表达的蛋白质的方法。 本发明的方法包括基于它们的物理特性(例如净电荷,分子量或免疫反应性)分离蛋白质,随后使用许多不同的技术检测所述蛋白质,包括i分枝扩增扩增方法RAM ii杂交信号放大法HSAM和iii用纳米点检测。 本发明的方法将具有各种不同的用途,包括但不限于筛选用途,疾病的诊断和预后。 本发明的方法特别可用于鉴定由于蛋白质的大小,蛋白质的低浓度或由于相似的物理性质而不能分离蛋白质而鉴定的蛋白质。
