Allgemeine Beschreibung
Anti-Digoxigenin-Fluorescein, Fab fragments has fab fragments from polyclonal anti-digoxigenin antibodies, conjugated to fluorescein.
Spezifität
The polyclonal antibody from sheep is specific to digoxigenin and digoxin and shows no cross-reactivity with other steroids, such as human estrogens and androgens.
Anwendung
Anti-Digoxigenin-Fluorescein, Fab fragments are used for the detection of digoxigenin-labeled compounds using:
- Digoxigenin-labeled sugars in glycoconjugate research
- Fluorescent in situ hybridization (FISH)
- Immunohistocytochemistry
- In situ hybridization
Angaben zur Herstellung
- Working concentration: Working concentration of conjugate depends on application and substrate. The following concentrations should be taken as a guideline:Detection of digoxigenin-labeled sugars in glycoproteins: 50 to 20μg/ml
- Fluorescent in situ hybridization (FISH): 1 to 20μg/ml
- Immunohistocytochemistry: 20 to 50μg/ml
- In situ hybridization: 20 to 50μg/ml
The anti-DIG anitbody is highly specific and sensitive. Therefore, for FISH, a concentration of 1μg/ml is sufficient, and only in case of critical probes, this concentration may be raised to <10μg/ml (with a distinct background to be expected).
Working solution: Reconstitution
Add 1 ml double-distilled water to a final concentration of 200μg/ml.
Blocking:
PBS, 0.5% bovine serum albumin (w/v), pH 7.4.
1% Blocking reagent (w/v), 1 to 5% heat inactivated fetal calf serum (v/v) or sheep normal serum can be used for reduction of unspecific binding. Furthermore, pH can be increased up to pH 8.5 to 9.0.
Storage conditions (working solution): Always prepare fresh!
After immunization with digoxigenin, sheep IgG was purified by ion-exchange chromatography, and the specific IgG was isolated by immunosorption. The Fab fragments obtained by papain digestion were purified by gel filtration, conjugated to the specific label, and stabilized in buffer.
Rekonstituierung
Add 1 ml double-distilled water to a final concentration of 200 μg/ml.

The investigation of inherited disorders of erythropoiesis has elucidated many of the principles underlying the production of normal red blood cells and how this is perturbed in human disease. Congenital Dyserythropoietic Anaemia type 1 (CDA-I) is a rare form of

Rainbowfishes (Melanotaeniidae) are the largest monophyletic group of freshwater fishes occurring in Australia and New Guinea, with 112 species currently recognised. Despite their high taxonomic diversity, rainbowfishes remain poorly studied from a cytogenetic perspective. Using conventional (Giemsa staining, C banding

DNA replication in mammals is regulated via the coordinate firing of clusters of replicons that duplicate megabase-sized chromosome segments at specific times during S-phase. Cytogenetic studies show that these "replicon clusters" coalesce as subchromosomal units that persist through multiple cell

Telomeres protect the ends of linear genomes, and the gradual loss of telomeres is associated with cellular ageing. Telomere protection involves the insertion of the 3' overhang facilitated by telomere repeat-binding factor 2 (TRF2) into telomeric DNA, forming t-loops. We
