    摘要: The present disclosure provides methods and systems for various uses of cell-free nucleic acid (cfNA). Functional typing of cfNA fragmentation patterns may be utilized in the non-invasive detection, diagnosis, and monitoring of disease. One embodiment may determine a stage of cancer in a subject, the progression of cancer in a subject, or the responsiveness to treatment of a cancer in a subject. Another embodiment disclosed herein may include sequencing-free diagnostic methods.

    摘要: Labeled nucleotide analogs comprising at least one avidin protein, at least one dye-labeled compound, and at least one nucleotide compound are provided. The analogs are useful in various fluorescence-based analytical methods, including the analysis of highly multiplexed optical reactions in large numbers at high densities, such as single molecule real time nucleic acid sequencing reactions. The analogs are detectable with high sensitivity at desirable wavelengths. They contain structural components that modulate the interactions of the analogs with DNA polymerase, thus decreasing photodamage and improving the kinetic and other properties of the analogs in sequencing reactions. Also provided are nucleotide and dye-labeled compounds of the subject analogs, as well as intermediates useful in the preparation of the compounds and analogs. Compositions comprising the compounds, methods of synthesis of the intermediates, compounds, and analogs, and mutant DNA polymerases are also provided.

    摘要: A method for clustering nucleotide strings of DNA strand replicas in clusters, comprising, for each pair of a first nucleotide string and a second nucleotide string, carrying out: arranging a matrix wherein each matrix element corresponds to a selected nucleotide in the first nucleotide string and to a further selected nucleotide in the second nucleotide string and is configured to store a calculated edit value indicative of an edit distance; progressively filling the matrix by storing calculated edit values; if the edit value calculated for a matrix element belonging to an output diagonal of the matrix is not lower than a cluster threshold, stopping said progressively filling and placing said first and second nucleotide strings in two different clusters, said output diagonal comprising the matrix element corresponding to the last column and the last row of the matrix.
