Chemical modification of biological sequences is important in many fields such as polypeptide drugs, gene therapy, viral vectors, etc. Both researchers and IP personnel pay attention to the specific modification of the sequence described in the text, including modification position, and chemical group type. At the same time, in a patent, there will be different modification methods for the same sequence corresponding to different experimental results, which need to be clearly distinguished. At present, online chemical modification cannot directly display the position and type of chemical modification, and there is no distinction between different modification schemes of the same patent. You must currently go to the Sequence Detail page to view details of the modification and it is difficult to easily digest this information. Therefore, Where Chemically Modified is selected as 'Yes', a ”View Detail” link has been added to the Sequence Results and Detail pages to quickly view modification information. This will open a pop-up tab on the right, from which you can see more details and view modification information graphically.
