Click Chemistry Reagents | Bioorthogonal Tools for Conjugation – Page 3

Click chemistry is gaining popularity and has an impact on chemical biology, polymer chemistry, bioconjugation, and drug discovery. Our broad range of click chemistry reagents includes many azides, alkynes cyclic alkynes (like DBCO and BCN), Tetrazine, TCO, and ligands to speed up your studies in this ever-changing area. We also excel at customizing different linkers such as PEG linkers and peptide linkers, to offer the most suitable click chemistry answers for your unique needs.

Copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC): This makes it popular in chemistry and biology. But it has some problems. Copper can harm living things. Also, getting rid of extra copper from final products can be hard. These issues limit its use in touchy areas like making drugs. These drawbacks make scientists want to find other options. Reactions using Tetrazine and TCO look promising. They avoid the problems that come with using copper.

Strain-promoted alkyne-azide cycloaddition (SPAAC): SPAAC has a big impact on bioorthogonal reactions seeing wide use in chemical biology, drug discovery, and materials science. Its power, speed, precision, and ability to work with biological systems make it a go-to choice. Unlike other reactions, SPAAC doesn't need outside catalysts or triggers to do its job. Instead, it relies on the built-in strain energy of cyclic alkynes to react with azides. This reaction proves helpful when paired with PEG linkers to boost stability and function in biological environments.

Inverse Electron Demand Diels–Alder (IEDDA) reaction: The IEDDA reaction the TCO ligation that Fox and his team created, excels due to its quick kinetics, orthogonality, and effectiveness in living systems. This reaction happens when an electron-deficient Tetrazine interacts with a strained TCO derivative making it ideal to use in living organisms.

By using our know-how in TCO, Tetrazine, and PEG linker technologies, we offer groundbreaking answers to push forward your click chemistry studies and uses.
