Li-Cor, the company of "environmental and biotechnology research systems", started to offer click chemistry reagents.
They combined click chemistry with its unique long-wavelength Infrared dyes. Dyes include: IRDye 800CW, TRDye 680RD, IRDye 650. Click chemistry gourps include: dibenzocyclooctyne (DBCO), azide and alkyne. The coupling of above (3x3) generated 9 reagents - for click chemistry in the field of in vitro or in vivo labeling and tracking of biomolecules. Options are available with copper-catalyzed and copper-free versions of click chemistry.
A webinar is provided for viewers.
