Live Cell Imaging Reagents

Cytoskeleton offers several reagents for live-cell research including fluorescent proteins, cell permeable protein activators and inhibitors, as well as our recent addition of live cell imaging probes. 

Spirochrome Probes For Bioimaging

Live-cell imaging probes developed by Spirochrome are cell-permeable compounds which stain microtubules (SiR-Tubulin), F-actin (SiR-Actin), Lysosomes (SiR-Lysosome) and chromosomal DNA (SiR-DNA) in living cells. 

Cytoskeleton is excited to introduce the next generation of Spirochrome’s live cell imaging probes - the SPY™ probes. SPY™ probes improve upon the SiR live cell imaging technology while also expanding the fluorophore labeling options for the study of F-actin, microtubules, and DNA in living cells.

MemGlow™ Probes For Bioimaging: From The MemBright Family Of Probes

Cytoskeleton is proud to announce 5 new bright fluorogenic probes to visualize the cellular plasma membrane.  Originally developed as the MemBright probes,  MemGlow™ probes are highly photostable, fluorogenic, and non-toxic to cells.

MemGlow™ probes are highly efficient and allow scientists to visualize cellular nanostructures with nanomolar probe concentrations.
