The level of cell proliferation provides insights into relative cell health and is a widely used diagnostic indicator for numerous cancer types. In immunology, measuring cell proliferation is particularly useful for assessing immune responses such as T cell activation. In the past, cell proliferation assays involved radioactive labelling of DNA, but today fluorescent dyes such as ViaFluor® SE and CFSE are a safer and easier alternative for tracking cell replication in vivo and in vitro.
Cell proliferation of peripheral blood mononuclear cells (PMBCs) can be a useful read-out of immune cell activation. In this Tech Tip, we outline a typical procedure for using fluorescent ViaFluor® SE Dyes with PMBCs, which can easily be adapted for use with other cell types.
