Launched just over a year ago, SiR-Actin (Fig 1) and SiR-Tubulin (Fig 2) have been available on the market providing the most convenient tools to stain F-actin and Microtubules in living cells. In the meantime, Spirochrome have launched a third stain based on the SiR-technology – SiR-DNA (Fig 3) to stain DNA in living cells.
These stains meet the central requirements for live cell imaging tools:
- high selectivity
- minimal toxicity
- fluorogenic for wash-free imaging
- applicable in different cell types and tissues
- excited by far-red light
- suitable for super-resolution microscopy
