摘要:
The invention provides methods for diagnosing diseases such as cancer and other conditions using biological samples. Liquid Tissue samples prepared from histopathologically prepared tissue obtained from a subject surprisingly can be used to identify and, optionally, to quantify analytes that are diagnostic of the presence of a disease, condition or syndrome in the subject.
摘要:
The invention provides methods for multiplex analysis of biological samples of formalin-fixed tissue samples. The invention provides for a method to achieve a multiplexed, multi-staged plurality of Liquid Tissue preparations simultaneously from a single histopathologically processed biological sample, where the protocol for each Liquid Tissue preparation imparts a distinctive set of biochemical effects on biomolecules procured from histopathologically processed biological samples and which when each of the preparations is analyzed can render additive and complementary data about the same histopathologically processed biological sample.
摘要:
The current invention provides a method for directly converting histopathologically processed biological samples, tissues, and cells into a multi-use biomolecule lysate. This method allows for simultaneous extraction, isolation, solublization, and storage of all biomolecules contained within the histopathologically processed biological sample, thereby forming a representative library of said sample. This multi-use biomolecule lysate is dilutable, soluble, capable of being fractionated, and used in any number of subsequent experiments.

摘要:
A method of laser forward transfer is disclosed. Photo energy is directed through a photon-transparent support and absorbed by an interlayer coated thereon. The energized interlayer causes the transfer of specific regions of a heterogeneous tissue sample coated thereon across a gap and onto a receiving substrate or into a receiving vessel.

This patent application discloses and describes a list of proteins that are found to be differentially expressed between normal endometrial epithelial cells and early stage cancerous endometrial epithelial cells. These proteins can be used either individually or in specific combinations in diagnostic and prognostic protein assays on various biological samples from endometrial cancer patients, or individuals suspected on having endometrial cancer. In addition, these proteins are also differentially expressed between normal endometrial epithelial cells and epithelial cells of other types of endometrial disease, and thus such diseases can be diagnosed using assays based on these proteins. The full length intact proteins can be assayed or peptides derived from these proteins can be assayed as reporters for these proteins. These proteins can also be identified as “companion diagnostic” proteins, wherein they are not only differentially expressed for use as diagnostic and prognostic indicators of endometrial cancer and other endometrial diseases, but the same proteins are also targets for therapeutic intervention of endometrial cancer and other endometrial diseases.

The current disclosure provides for specific peptides from the Insulin-Like Growth Factor 1 Receptor (IGF-1R) protein and the derived ionization characteristics of those peptides that are advantageous for quantifying the IGF-1R directly in formalin fixed biological samples by the method of Selected Reaction Monitoring (SRM) mass spectrometry. Such fixed biological samples include: formalin-fixed tissue/cells, formalin-fixed/paraffin embedded (FFPE) tissue/cells, FFPE tissue blocks and cells from those blocks, and formalin fixed and paraffin embedded tissue culture cells. IGF-1R protein is quantitated in biological samples by the method of SRM/MRM mass spectrometry by quantitating one or more of the peptides described herein. The peptides can be quantitated if they reside in a modified or an unmodified form. Examples of potentially modified forms of an IGF-1R peptides include those bearing phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.
