Application

Digoxigenin NHS-ester has been used in the preparation of streptavidin-digoxigenin conjugate and digoxin-recombinant Ara h1 (peanut component) conjugate for enzyme-linked immunosorbent assay (ELISA) analysis.

Biochem/physiol Actions

Digoxigenin NHS-ester is an activated ester that reacts with amino groups under mild conditions, attaching the digoxigenin moiety to proteins or 5′-amino substituted oligonucleotides Digoxigenin labeling is used to immuno-tag molecules for detection using anti-digoxigenin antibodies with high affinities and specificity.
Digoxigenin, an aglycon, is a pharmacologically active plant toxin. It is less potent than digoxin. It is used in lower doses to treat heart conditions. Digoxigenin is usually conjugated to another payload which reduces its remaining activity or accessibility to tissues. Since digoxigenin is permanently bound and entirely covered by the capture modules, it cannot be used as an active entity.

The digoxigenin derivative N-hydroxysuccinimidyl digoxigenin-3-O-methylcarbonyl-epsilon-aminocaproate (HDMA) has been shown to covalently label the ouabain binding site of the Na,K-ATPase epsilon subunit [Antolovic et al. (1995) Eur. J. Biochem. 227, 61-67]. In the present study we observed both, labeling and inactivation

Bispecific antibodies that bind cell-surface targets as well as digoxigenin (Dig) were generated for targeted payload delivery. Targeting moieties are IgGs that bind the tumor antigens Her2, IGF1R, CD22, or LeY. A Dig-binding single-chain Fv was attached in disulfide-stabilized form

Na+/K(+)-ATPase from pig kidney is inactivated by protein-reactive N-hydroxysuccinimidyl derivatives of digoxigenin. Like digoxigenin, its protein-reactive derivatives N-hydroxysuccinimidyl digoxigenin-3-methylcarbonyl-epsilon-aminocaproate (HDMA), 3-amino-3-deoxydigoxigenin hemisuccinimide succinimidyl ester (ADHS), 3-iodoacetylamino-3-deoxydigoxigenin (IAD) and digoxigenin-3-O-succinyl-[2-(N-maleimido)]ethylamide (DSME) inhibited the sodium pump in the presence of Na+, Mg2+
