SiR700-tubulin is based on the silicon rhodamine (SiR) fluorophore analogue SiR700 and the microtubule binding drug Docetaxel. SiR700-tubulin allows the labelling of microtubules in live cells with high specificity and low background. The key features of SiR700-tubulin are far-red
absorption and emission wavelengths,cell permeability and compatibility with superresolution microscopy (STED & SIM).
