Tubulin Tracker Green (Oregon Green 488 Taxol, bis-acetate) provides green-fluorescent staining of polymerized tubulin in live cells. Tubulin Tracker Green is an uncharged, non-fluorescent compound that easily passes through the plasma membrane of live cells. Once inside the cell, the lipophilic blocking group is cleaved by non-specific esterases, resulting in a green-fluorescent, charged form, inhibiting it from escaping the live cells. TubulinTracker Green reagent utilizes Oregon Green 488 dye, which absorbs and emits optimally at 494 nm and 522 nm, respectively, and fluorescence can be visualized with standard GFP/FITC filter settings using almost any fluorescent imaging instrument. It can be multiplex with blue, orange, red, deep-red, and near-IR fluorophores.
