Spirochorme introduces the new SiR-reagent SiR-BCN for click chemistry with tetrazine and azide derivatives.


05 September 2016

Spirochrome proudly launches the brand new and further red emitting SiR700 probes for actin, DNA and microtubules. SiR700 probes allow dual colour imaging experiments in live cells and dual colour superresolution imaging with STED and SIM. In addition, two new fluorogenic live cell probes for lysosomes are introduced: SiR-lysosome and SiR700-lysosome. The probes were published by the Johnsson group in JACS:  http://pubs.acs.org/doi/abs/10.1021/jacs.6b04782.
