Abstract:
Immunocytochemistry (ICC) is a sensitive and powerful method that is used to localize and identify cells containing a particular antigen. This chapter is dedicated to ICC of suprachiasmatic nucleus (SCN) slices. After a brief introduction to the technique, the materials and methods sections describe two different methods to obtain SCN slices--the first one for fixed tissue, the second one for fresh frozen tissue--followed by the description of two methods of antibody detection: the indirect method and the avidin-biotin complex one. In addition, some remedies to the most common problems encountered while performing ICC and some alternative protocols are discussed.
