50 results about "RNA analysis" patented technology

One of the most common and basic types of RNA analysis is sequence analysis. RNA is made up of four types of molecules known as nucleotides: adenine, guanine, cytosine, and uracil. Determining the sequence of nucleotides in such chains of RNA allows researchers to predict the structure of a resulting protein or to look for mutations in the sequence.

Integrative single-cell and cell-free plasma RNA analysis

Embodiments of the present technology involve integrative single-cell and cell-free plasma RNA transcriptomics. Embodiments allow for the determination of expressed regions that can be used to identify, determine, or diagnosis a condition or disorder in a subject. Methods described herein analyze cell-free RNA molecules for certain expressed regions. The specific expressed regions analyzed were previously determined to be indicative for a certain type of cell or grouping of cells. As a result, the amounts of cell-free reads at the specific expressed regions may be related to the number of cells in a tissue or organ. The number of cells in the tissue or organ may change as a result of cell death, metastasis, or other dynamics. A change in the number of cells in the tissue or organ may then be reflected in certain expressed regions in cell-free RNA.
