Biotin-PEG2-alkyne is a click chemistry biotinylation tool. This reagent allows the labeling of azide-containing molecules with biotin via copper-catalyzed click reaction. Biotin-labeled biomolecules can be bound to avidin or streptavidin for further purification and detection.

This structure of biotin alkyne features a hydrophilic PEG2 linker that separates biotin residue from the target molecule for efficient binding with streptavidin. Its linker also enhances aqueous solubility to facilitate conjugation.

THPTA ligand

THPTA is a water-soluble ligand for Cu(I)-catalyzed click chemistry. The ligand stabilizes copper in its Cu(I) oxidation state. Due to high aqueous solubility, reactions with this ligand do not require an organic co-solvent.

Biotin alkyne

Biotin alkyne is a reactive affinity label which can be attached to biomolecules via click reaction.
