SiR700-tubulin is based on the microtubule binding drug Docetaxel. SiR700-tubulin is fluorogenic, cell permeable and highly specific for microtubules. Sir700-tubulin stains endogenous microtubules without the need for genetic manipulation or overexpression. Its emission in the far red minimizes phototoxicity and sample autofluorescence. SiR-tubulin is compatible with GFP and/or m-cherry fluorescent proteins. It can be imaged with standard Cy5 filtersets. SiR700-tubulin can be used for widefield, confocal, SIM or STED imaging in living cells and tissue. Probe quantity allows 50 – 200 staining experiments.*
In combination with standard SiR-probes, SiR700-actin allows dual colour imaging experiments in live cells. For more information please visit www.spirochrome.com/dualcolour.
