Bifunctional reactive PEG4-based crosslinker containing terminal alkyne group for click chemistry or Sonogashira coupling and reactive alkyl iodide group.

Water soluble, heterobifunctional hydrophilic linker with a length of 14 Å, containing maleimide for thiol labeling, and alkyne for click chemistry. An ideal reagent to attach an alkyne moiety to a protein.

Non-reactive form of AF 594 fluorescent dye with a free carboxyl group.

Red-fluorescent NHS-ester of AF 594 dye for labeling proteins, peptides, antibodies, and any molecules containing an -NH2 group. Pure 5-isomer

AF 594 conjugate of streptavidin, a high-affinity biotin-binding protein, for immunofluorescence, western blots, microplate assays, and other applications use.

Tetrazine derivative of AF 594 fluorophore for TCO ligation and in vitro labeling.

A tyramide derivative of AF 594, a red fluorescent reagent widely used for tyramide signal amplification (TSA) in IHC, ICC, and FISH.

An amine-functionalized AF 647 dye for coupling with activated esters and epoxides.

Bright and photostable azide AF 647 for labeling alkyne-containing biomolecules and fluorescent visualization of biological objects.

AF 647 carboxylic acid is a water-soluble dye that can be used as a reference standard for dye conjugates and the synthesis of AF647-containing biomolecules.
