IA-Alkyne

Biological Activity

IA-Alkyne is a broad spectrum cysteine reactive probe. Covalently binds cysteine residues in proteins. Can be utilized for covalent fragment-based ligand discovery (FBLD) and to identify Zn²⁺-binding cysteines. Used as a click-chemistry handle to attach a fluorophore or biotin to reactive cysteines in proteins for visualization by in-gel fluorescence or identification by mass spectrometry, respectively. Covalently binds cysteine residues in and activates TRPA1 channels.
