Contributions to Arabinogalactan Protein Analysis.

Arabinogalactan proteins (AGPs) are important plant proteoglycans involved in many development processes. In roots, AGPs occur in the cell wall of root cells and root cap-derived cells as well as in the secreted mucilage. Detection, localization , and quantification techniques are therefore essential to unravel the AGP diversity of structures and functions. This chapter details root-adapted immunocytochemical methods using monoclonal antibodies, and a collection of biochemical analysis protocols using β-D-glucosyl Yariv reagent for comprehensive AGP characterization.
