Radioactively labeled peptides provide a highly-sensitive detection method without common problems associated with other labeling methods, such as spurious fluorescence, enzymatic activity, or steric problems. Design your own radioimmunoassay or ligand binding study with I-125 and 3-H labeled peptides.
Custom peptides can also be synthesized with modification by acetylation, phosphorylation, amidation, succinylation, butyrylation and specific disulfide bridge cross-linking.
