Stripping with TCEP for 45 minutes can remove the fluorescence from many common dyes/secondaries (not mitotracker) to allow for multiple staining cycle of the same cells/tissues.

A very cool article where Graham et al use the cell painting technique to follow liver cell lineages across different treatments and time.
pubmed.ncbi.nlm.nih.gov
We have developed a single-cell assay that combines Cell Painting-a morphological profiling assay-with trajectory inference analysis. We have applied this morphological trajectory inference to the...
