- Streptolysin O, a bacterial toxin which forms temporary pores in the membrane and allows delivery of virtually any fluorescent probes, ranging from labeled IgG’s to small ligands, with high efficiency (>85% of cells). The whole process, including recovery, takes 30 min, and the cell is ready to be imaged immediately.
- Oxyrase, a cell-friendly photostabilizer, a ~20x improvement in fluorescence photostability is achieved.
