The study of cell signaling involves moving between different levels of focus, from the behavior of individual proteins to signaling pathways to massive, interconnected systems. Antibodies are important tools at every level, but all antibodies are not the same. The quality, purity, and specificity of the antibodies used can make a crucial difference in the results of an experiment. As well, many antibodies for cell signaling are targeted to specific methods and applications, such as immunofluoresence, microarray, or ELISA. For studies of individual proteins in signaling pathways, a single, high quality antibody may be sufficient. Antibodies are also available in the form of panels for looking at whole signaling pathways at once. The information on this page can help you choose the right antibodies for your cell signaling work.
