Wood fibers are composed mainly of cellulose,
hemicellulose and lignin. Fiber properties such as
bonding ability are largely governed by surface chemistry
of fibers. FTIR and ESCA have been applied for analysis
of wood fibers and papers, but these methods do not give
information on the surface distribution of components.
Microscopy offers a linkage between chemistry and
structure with methods for distinctive and specific
staining or labelling of fiber components. Antibodies can
be used as specific markers for different carbohydrates.
They have been produced against oligosaccharides obtained
from xylan and xyloglucan (Takahashi and Sumiya, 1990,
Sone and Sato, 1994). Also polysaccharides have been used
as antigen (Moore, 1989, Knox et al., 1990, Westermark
and Vennigerholz, 1995).
