KP-1 dye distinguishes stem cells from differentiated cells by LCI and FCM
Live cell imaging and cell sorting by flow cytometry are possible experimental approaches for researchers working in stem cell research and regenerative medicine. In this post, we take a look at the Kyoto Probe 1 (KP-1) from (GORYO Chemicals).
KP-1 is a unique chemical probe to distinguish Human stem cells (iPS / ES cells) from differentiated cells in culture and by LCI or FCM.
This is possible because of KP-1’s characteristics (ex. 515 nm, em. 529 nm) and the fact that ABC transporters are active in differentiated cells.
Cell permeable, the dye enters into the the human pluripotent stem cells and localizes in the mitochondria (regardless of the mitochondrial membrane potential) leading to a fluorescent staining in the cells. After cellular differentiation, active ABC transporters eliminate KP-1 from the cells which become non-fluorescent.
KP-1 enables you to distinguish iPS cells from differentiated cells and to isolate human iPS cells from somatic cells (except nerve cells) by cell sorting. This probe is very useful for researchers involved in regenerative medicine and stem cell research.
