Project title Next generation sequencing methods for glycoconjugates

Project description: this project builds on a highly successful existing collaboration between the Manchester (existing collaboration between Flitsch/Barran and Field) and A*STAR laboratories (Nguyen-Khuong), including a current A-star studentship (2017-2020 to Ed Pallister). The student will use a combination of synthetic, analytical and computational techniques to develop a next generation sequencing platform for carbohydrates and glycoconjugates. The chemical synthesis of carbohydrates is challenging, but both the Flitsch and Field laboratories have developed enzymatic methodologies, which are easy to perform. The relevant enzymes will be provided from on-going projects. The synthetic analytes will be complemented throughout the project by commercial standards (provided by A*STAR) and at the end by ‘real’ biological samples (e.g. mixtures generated by glycoenzymes, biopharmaceuticals, glycolipids) to test performance. The second aspect of the project will focus on analytical techniques (existing collaboration between Flitsch and Barran), including chromatography, mass spectrometry and ion mobility spectrometry. Relevant instrumentation is available both in Manchester (where the student will be trained in year one) and at A*STAR, allowing for the seamless transition of know-how and
expertise and a cohesive research project. The third aspect of the project will involve computational methods, including applications of databases (some of which exist already) and computational tools to deal with structural identification through complex but unique data fingerprints that will be generated using the methods above. The project will be embedded in current activities both at Manchester and A*STAR .
