L-Azidohomoalanine (AHA) is a noncanonical amino acid analog of methionine that contains an azide moiety. AHA-labeling is a fast, sensitive, non-toxic, and non-radioactive alternative to the traditional technique for detecting nascent protein synthesis.

AHA is the cell-permeable compound randomly incorporated into synthesizing protein instead of methionine during translation. The resulting azide-labeled full-length proteins can be detected via copper-catalyzed click reaction (with fluorescent or biotin-labeled alkynes) or copper-free click reaction (with cycloalkynes) and used for subsequent microscopic imaging or purification tasks.

sulfo-Cyanine3 alkyne

A water-soluble dye alkyne for copper-catalyzed click chemistry. The fluorophore sulfo-Cyanine3 is a bright and photostable dye for the Cy3® channel.

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.

6-Carboxy-H2DCFDA (6-carboxy-2',7'-dichlorodihydrofluorescein)

A reagent for detecting reactive oxygen species (ROS) in living cells. This carboxylated H2DCFDA analog has two additional negative charges that impede its leakage out of the cell.
