This paper describes the immunohistochemical techniques which can be used to detect cytokines and cell adhesion molecules in synovial membrane tissue, including a list of reagents and possible problems in each technique. It also describes three methods of quantitation of the resultant immunohistochemical detection, including the recent innovation computer-assisted digital video image analysis, and lists the advantages and disadvantages of each quantitation technique. This information will be a useful summary for any scientist interested in applying such techniques to the detection of cytokines and cell adhesion molecules in human tissue sections.
