- 14:44Conclusion
The goal of the present protocol was to develop a method that will allow functional genomic analyses of mast cell secretion. The protocol is based on quantitative assessment of the release of a fluorescent reporter gene cotrasfected with the gene of interest and real time analyses of the secretory granule's morphology.
