Does Glen Research offer product for digoxigenin labelling of oligos?
RESPONSE:No. Digoxigenin labelling is covered by patents owned by Boehringer Mannheim, now Roche Molecular Biochemicals. In any case, the digoxigenin molecule contains a portion, necessary for antibody detection, which is very base-labile. A phosphoramidite procedure similar to biotin or fluorescein labelling would not therefore be possible.
