BP Fluor 430 Azide is a water-soluble, green-fluorescent, azide-activated probe that reacts with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctyne via a copper-free click chemistry reaction to form a stable triazole and does not require a Cu-catalyst or elevated temperatures. BP Fluor 430 is a bright, photostable, green-fluorescent probe with excitation near its absorption maximum at 432 nm and emission maximum at 539 nm. This probe is water soluble and pH-insensitive from pH 4 to pH 10. A next generation probe, BP Fluor 430 Picolyl Azide, is also available for detection of low abundance alkyne-tagged biomolecules.

Cyanine3B azide for click chemistry conjugation with terminal alkynes via a copper-catalyzed click reaction or strained cyclooctynes via a copper-free click reaction. Cyanine3B is a yellow-emitting cyanine dye that is an improved version of the Cyanine3 fluorophore with significantly higher fluorescence quantum yield and photostability. Due to the fixed conformation, Cyanine3B has the highest emission quantum yield compared to other dyes of this wavelength. This is a non-sulfonated dye that requires an organic co-solvent (DMF, DMSO, or other) for efficient labeling in water.

BP Fluor 350 Azide is a blue-fluorescent, azide-activated probe that reacts with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctyne via a copper-free click chemistry reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. BP Fluor 350 is a water-soluble, moderately photostable, blue-fluorescent probe optimally excited by the 350 nm laser line. It is routinely used for generation of stable signal in imaging and flow cytometry. The brightness and photostability of blue dyes are best suited to direct imaging of high-abundance targets.

BP Fluor 555 Azide is a water-soluble, bright orange-fluorescent dye with excitation ideally suited for the 532 nm or 555 nm laser lines and visualized with TRITC (tetramethylrhodamine) filter sets. BP Fluor 555 conjugates of antibodies, peptides, and proteins are pH insensitive from pH 4 to pH 10. AF 555 conjugates ideally suited for detection of low abundance targets. BP Fluor 555 Azide can be reacted with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctyne via a copper-free “click chemistry” reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. The brightness and photostability of this dye are best suited to direct imaging of low-abundance targets.

BCN-PEG6-OH is a neutralizing agent and anticoagulant inhibitor containing strained alkyne. BCN-PEG6-OH undergoes strain-promoted alkyne-azide cycloaddition (SPAAC) click reaction with azido-Warfarin to generate an inactive product that can be rapidly cleared via the kidneys. In mice, BCN-PEG6-OH effectively reduces the anticoagulant activity of azido-Warfarin in a dose-dependent manner, normalizes prothrombin time, and exhibits no inherent anticoagulant or procoagulant effects when administered alone. BCN-PEG6-OH can be used for the research of drug-induced coagulopathy .

PreQ1-DBCO is a strained cyclooctyne commonly used in click chemistry. PreQ1-DBCO undergoes TGT-catalyzed guanine base exchange in DNA oligonucleotide stem-loops to replace guanine. PreQ1-DBCO functionalizes custom DNA oligonucleotide sequences. DBCO-modified DNA oligonucleotides are conjugated with azide peptides via strain-promoted azide-alkyne click chemistry (SPAAC). PreQ1-DBCO can be used in studies of hemophilia B (Christmas disease) .
