KB05yne
Based on 1 Customer Validation
KB05yne is a site-selective, alkyne-functionalized electrophilic "probe" fragment probe designed for covalent ligand discovery, with preferential reactivity toward specific cysteine residues in proteins. KB05yne strongly labels wild-type target proteins (e.g., CDKN2AIP, HPCAL1) but does not label their cysteine-to-alanine mutants, confirming site-specific cysteine reactivity. KB05yne can be used for the discovery and optimization of site-specific covalent ligands, and is applicable to proteins with diverse structures and functions, especially in studies targeting cysteine residues in cancer-related or difficult-to-purify proteins.
