Understanding the dynamic processes of glycosylation is fundamental to many areas of biology and medicine. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer N-azidoacetylgalactosamine-tetraacylated (Ac4GalNAz, CAS: 653600-56-7), a key reagent that acts as a gateway to deeper insights into glycosylation via metabolic labeling.

Metabolic labeling involves introducing modified molecules into living cells or organisms that are then incorporated into specific cellular components. Ac4GalNAz excels in this role within the realm of glycobiology. As an unnatural sugar analog, it is recognized and processed by cellular machinery, effectively replacing its natural counterpart, GalNAc, and thereby introducing an azide tag into newly synthesized glycoproteins.

This strategic incorporation of an azide group is what makes Ac4GalNAz so powerful. The azide is a highly bioorthogonal functional group, meaning it can react specifically with complementary functional groups, such as alkynes, without interfering with native biological processes. This orthogonality is the cornerstone of N-azidoacetylgalactosamine-tetraacylated metabolic labeling.

The subsequent detection of these labeled glycoproteins can be achieved through various bioconjugation strategies, most notably click chemistry. This allows for the attachment of diverse labels, including fluorescent probes for imaging or affinity tags for pulldown assays. The ease of handling and enhanced solubility provided by the acetyl groups further streamline the experimental workflow, making Ac4GalNAz click chemistry a preferred method for many research groups.

By employing Ac4GalNAz, scientists can track the synthesis, trafficking, and function of specific glycoproteins. This makes it an invaluable tool for studying cellular processes, identifying biomarkers, and developing targeted therapeutics. The development of effective metabolic glycoengineering tools, like Ac4GalNAz, is crucial for advancing our understanding of biological systems.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to facilitating groundbreaking research by supplying high-quality pharmaceutical intermediates. We believe that Ac4GalNAz represents a critical component for anyone looking to explore the intricacies of glycosylation through precise and efficient metabolic labeling.
