Cell Surface-based Metabolic Conjugation Service

Working together, chemists and biologists will be able to develop methods that combine genetic and metabolic engineering to introduce a range of unnatural epitopes onto cells without the restrictions imposed by nature’s biosynthetic machinery and metabolic building blocks. Advances in these technologies will also produce new, multifaceted tactics for landscaping cell surfaces. The potential for these techniques is tremendous. As a professional cell surface engineering services provider, Creative Biolabs is capable of providing customer-satisfied cell surface-based metabolic conjugation services to global clients.

Introduction of Cell Surface-based Metabolic Conjugation

Much of enzyme-mediated labeling requires some aspects of time-intensive genetic engineering for tagged substrates. The continued pursuit of imparting orthogonality without the use of genetic manipulation has ignited the field of metabolic engineering. It is now possible to create new cell-surface epitopes via the metabolic incorporation of unnatural precursors into plasma membrane components. Oligosaccharides are particularly amenable to this type of metabolic engineering since the enzymes and transport proteins in certain biosynthetic pathways are tolerant of unnatural substrates. Cells will take up monosaccharide analogs from the extracellular environment and process them into cell-surface glycoconjugates. In contrast, the pathways for protein biosynthesis are more restrictive, and only the most conservatively modified amino acids are accepted.
