NIR fluorescent dye functionalized with cyclooctyne moiety for copper free click chemistry conjugation with azides.

Activated ester for modification of proteins/antibodies/peptides followed by introduction into copper-free click chemistry reaction.

Phosphoramidite derivative of Cyanine5 for use in oligonucleotide synthesis.

Cyanine5 is a universal red emitting dye with a very high extinction coefficient, and good quantum yield. This tetrazine derivative reacts very quickly with trans-cyclooctenes and cyclopropenes with the formation of stable conjugates.

Reactive near infrared (NIR) dye for click chemistry containing a terminal alkyne group.

Near-infrared dye Cyanine7.5 with free amino group which can be coupled with activated carboxylic acid derivatives.

Long-wavelength NIR fluorescent dye azide for click chemistry.

Cyanine7.5 carboxylic acid – unactivated NIR cyanine dye carboxylic acid.

Non-functionalized Сyanine7.5 dye derivative with an aliphatic side chain.

Near infrared fluorophore functionalized with hydrazide moiety. Reactive against carbonyl compounds, useful for the labeling of saccharides, and antibodies after periodate oxidation.
