From the authors: "Our results reveal that reversible photobleaching accounts for the majority of titin recovery in the titin-mEos3.2 hiPSC-CM model and should warrant as a caution in the extrapolation of reliable FRAP data from specific fluorescent proteins in long-term cell imaging.” 

This study is highlighted as one of January's "best of the best" as part of the American Physiological Society's APSselect program.
