Abstract
Constitutive secretion is predominantly measured by collecting the media from cells and performing plate-based assays. This approach is particularly sensitive to changes in cell number, and a significant amount of effort has to be spent to overcome this. We have developed a panel of quantitative flow cytometry-based assays and reporter cell lines that can be used to measure constitutive secretion. These assays are insensitive to changes in cell number making them very robust and well suited to functional genomic and chemical screens. Here, we outline the key steps involved in generating and using these assays for studying constitutive secretion.
