(poly-l-lysine)y(mimhnk-1)x
"A random copolymer based on poly-L-lysine containing a disaccharide glycomimetic of the natural HNK-1 (human natural killer-1) glycoepitope. The proportions of the HNK-1 glycomimetic-modified poly-L-lysine component and the unmodified poly-L-lysine component (labelled m and m respectively in the diagram) are respectively x% and (100-x)%."
