Product Details

Biological Activity

Green fluorescent taxol derivative. Used for microtubule imaging. Binds microtubules with high affinity (Ka ~ 107M-1). Excitation/emission maximum λ ~ 496/526 nm.

Flutax 2-labeled HeLa Cells


Application of Flutax 2: Flutax 2 was diluted in HBSS and applied to live HeLa cells at a concentration of 2 �M. HeLa cells were incubated for 1 hour at 37�C. After incubation was complete, Flutax 2 was washed off, and fresh HBSS was applied to the cells. Cells were not fixed because Flutax 2 staining is not retained at all after fixation (photobleach). Like Flutax 1, Flutax 2 staining in live cells diminishes very rapidly when exposed to light, so the cells should be exposed to light as little as possible to retain good signal.
