Mast cells are important effector cells of the immune system. We describe a rapid and inexpensive microassay to determine histamine release from human gingival mast cells. The assay is based on the coupling of histamine with o-phthalaldehyde (OPT) at a highly alkaline pH to form a fluorescent product. Using this assay with a sample volume of 10 microl/well in a 384 black well microplate, the histamine detection limit was 0.031 microg/ml. The human mast cell line (HMC-1) and fresh mast cells isolated from human gingival tissue (n = 10) were stimulated with substance P, anti-IgE or calcium ionophore A23187. Calcium ionophore significantly increased histamine release from HMC-1 cells and gingival mast cells (p < 0.05). This microassay will facilitate the study of mast cell histamine release in diseased oral mucosa.
