Measurement of mast cell cytokine release by multiplex assay

Mast cells are highly responsive cells that are capable of secreting a variety of inflammatory mediators, including histamine, heparin, serine proteases, leukotrienes, prostaglandins, and thromboxanes. Studies from several laboratories have demonstrated that mast cells have the capacity to produce a variety of cytokines in response to various stimuli. Characterization of the cytokine profiles in mast cells has routinely been determined by the performance of individual enzyme-linked immunosorbent assays. This process is expensive, time-consuming, and requires a great deal of material to characterize multiple cytokines. In this chapter, we describe a multiplex cytokine assay to detect 17 cytokines simultaneously in 50 microL of culture supernatant derived from stimulated human cord blood-derived mast cells.
