Innovative Techniques Developed in Bertozzi’s Research Lab
One of the hallmark contributions of Bertozzi’s lab is the development of bioorthogonal chemistry, a set of chemical reactions that occur inside living organisms without interfering with native biochemical processes. This innovative technique allows researchers to label and visualize glycans in live cells, providing unprecedented insight into the dynamics of glycan biology. By employing bioorthogonal reactions, Bertozzi’s lab has enabled the tracking of glycan modifications in real time, enhancing our understanding of how glycans function in various biological contexts.
Additionally, Bertozzi’s lab has pioneered the use of click chemistry—a method that facilitates the rapid and efficient joining of molecules—to study glycans. This approach has proven to be valuable in synthesizing glycan probes that can be used to investigate glycan interactions and their roles in cellular processes. With click chemistry, researchers can create highly specific glycan structures, allowing for detailed studies on how these molecules influence cell behavior, adhesion, and signaling pathways.
The combination of bioorthogonal chemistry and click chemistry has positioned Bertozzi’s lab at the forefront of glycobiology research. Researchers in her lab have also developed innovative imaging techniques that utilize these chemical methods to visualize glycan distribution and dynamics in tissues and living organisms. This comprehensive toolkit of methodologies not only accelerates research in glycobiology but also enhances collaboration across various scientific disciplines.
