Spectroscopic methods provide a powerful tool for studying the properties o
f proteins at interfaces. The protein accumulated in one adsorbed layer is
frequently less than the minimum mass of protein required by a detection me
thod. In such a case las is the case in circular dichroism spectroscopy) th
e sorbent material is usually supplied as dispersion. However, light scatte
ring by the dispersed particles often interferes with the measurement of th
e circular dichroism of the protein. Therefore, there is a strong need for
an experimental setup that enables these measurements to be made using flat
surfaces. An example of such a setup is the multiplate quartz cell present
ed here. The potential of this multiplate quartz cell is shown by some prel
iminary circular dichroism measurements of IgG adsorbed on different types
of surfaces. (C) 2000 Academic Press.
