New paper from @zhixingchen2.bsky.social's lab!
It turns out that, in addition to its very low phototoxicity, PKmito Deep Red (PKMDR) directly reports on mitochondrial membrane potential (MMP) in live cells through its lifetime!

Live cell ACTIN imaging has never been easier with SPY650-FastAct_X!
1. Add the probe to the cells
2. Image 1h later
SPY650 is highly suited for STED imaging. The image shows a confocal/STED comparison of the fine actin mesh in a live HeLa cell.
