Technical Data
Digoxigenin (HRP)
Digoxigenin is considered a hapten, a small molecule with high immunogenicity used in many molecular biology applications. Other popular haptens include DNP (dinitrophenol), biotin, and fluorescein. In general, antibodies generated against haptens have higher affinities for their targets than other antibodies, so haptens are conjugated to other biological molecules as all-purpose immuno-tags. This is because anti-hapten antibodies have high affinities and are readily available, while antibodies may not be commercially available for exotic biological targets. Digoxigenin is a standard immunohisto- chemical marker for in situ hybridization. In this case it is conjugated to a single species of RNA nucleotide triphosphate (typically Uridine), which is then incorporated into RNA (a "riboprobe") as it is synthesized by the cellular machinery. Later, the digoxigenin ("Dig") markers are detected with anti-digoxigenin antibodies, which may be labeled with dyes or enzymes (see ELISA) for visualization and detection. In a similar manner, digoxigenin may be conjugated to sugars to study glycosylation events in biological systems.

Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
ELISA: 1:1000-1:10,000
Western Blot: 1:500-1:5000
Immunohistochemistry (Frozen, paraffin): 1:10-1:2000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized powder may be stored at -20░C. Stable for 12 months at -20░C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20░C. Reconstituted product is stable for 12 months at -20░C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.áLabeled with horseradish peroxidase (HRP). Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates. HRP conjugates are sensitive to light.
