New Products!

Discover our new SiR-DNA kit: A far-red, fluorogenic, highly specific and non-toxic stain for DNA in live cells. SiR-DNA outperforms the most commonly used DNA stains in terms of specificity and toxicity. Long-term live cell imaging of DNA can now be performed without phototoxic blue excitation light or worrying about the toxicity of the stain. As all our other probes, SiR-DNA is compatible with superresolution microscopy. Read more about this amazing probe in the recent article in Nature Communications.

Spirochrome also introduces three new SiR-fluorophore derivatives for bioorthogonal click chemistry: SiR-tetrazine, SiR-azide and SiR-alkyne.
