Latest Patents

Lin He holds a patent for "Methods and systems for assembly of protein sequences." This patent describes a method for determining the amino acid sequence of a polypeptide or protein from mass spectrometry data. The process involves using a weighted de Bruijn graph to analyze extracted and purified proteins that are cleaved into a mixture of peptides. The peptides are then analyzed using mass spectrometry, and a list of peptide sequences is derived through de novo sequencing. The method also includes determining amino acid confidence scores based on peak fragment ion intensity. A weighted de Bruijn graph is constructed, with node weights defined by k−1 mer confidence scores, allowing for the assembly of at least one contig from the graph.
