Latest Patents

Ivan K Chu holds a patent for a method titled "Sequencing of peptides by mass spectrometry." This strategy focuses on the semiautomatic sequencing of argentinated oligopeptides. The method utilizes a search algorithm to identify a triplet peak relationship in the product ion spectrum of the [M+Ag] ion of an oligopeptide. The ions that form a triplet include [b +OH+Ag], [b -H+Ag], and [a -H+Ag], which are separated by 18 and 28 m/z units. The differences in the m/z values of adjacent triplets help identify the residue that is cleaved, while the observation of the [y +H+Ag] ion containing the cleaved residue confirms the assignment. This patent showcases his expertise and innovative thinking in peptide sequencing.
