Conjugation of LPS-Derived Oligosaccharides to Proteins Using Oxime Chemistry
Time of Update: 2020-11-23
This chapter describes a method for coupling low-molecular mass lipopolysaccharide (LPS)-derived oligosaccharides composed of a core or a short O-specific polysaccharide-core fragment (O-SPC) to a carrier protein by a single-point attachment.
Consequently, this method is highly suitable for the preparation of LPS-based human vaccines.
