Structure of the Carbohydrate Units of IgA1 Immunoglobulin

Abstract

the structure of the two asparagine-linked oligosaccharide units of an IgAl myeloma protein was defined.In this paper we present data which establish the structure and linkage points of the five Oglycosidically linked oligosaccharide units found on the CX~ subtype heavy chain to be as shown below.
