question: What is the application of the Bimolecular Fluorescence Complementation (BiFC) assay in Drosophila embryos?
answer: Bimolecular fluorescence complementation (BiFC) is a powerful method for studying protein-protein interactions in different cell types and organisms. This method was recently developed in the fruit fly Drosophila melanogaster, allowing analyzing protein interaction properties in a physiologically relevant developing context.
