General description
Fab fragments from polyclonal anti-fluorescein antibodies, conjugated to horseradish peroxidase. The reagent is an anti-fluorescein antibody, Fab fragments from sheep, conjugated with horse-radishperoxidase (POD). After immunization with fluorescein the sheep IgG (immunoglobulin G) 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 with POD and stabilized in 60mM Tris-Hepes-buffer, 0.4% bovine immunoglobulin (w/v), 0.2% Germall II (w/v), pH 7.2.
Specificity
The polyclonal antibody reacts with free and bound fluorescein.
Application
Anti-Fluorescein-POD, Fab fragments are used for detection of fluorescein-labeled compounds in:
- Dot blot
- ELISA (enzyme-linked immunosorbent assay)
- Immunohistocytochemistry
- In situ hybridization
- Southern blot
- Western blot
Preparation Note
Working concentration: Working concentration of conjugate depends on application and substrate. The following concentrations should be taken as a guideline:
Working solution: 100 mM Tris-HCl, 150 mM NaCl, pH 7.5. If necessary 1% Blocking reagent (w/v), dry milk powder, 1 to 5% heat inactivated fetal calf serum (v/v) or sheep normal serum can be used for reduction of unspecific binding.
- Dot blot: 150 mU/ml
- ELISA: 50 to 150 mU/ml
- Immunohistocytochemistry: 250 to 500 mU/ml
- In situ hybridization: 1.5 to 7.5 U/ml
- Southern blot: 150 mU/ml
- Western blot: 500 to 1000 mU/ml
Working solution: 100 mM Tris-HCl, 150 mM NaCl, pH 7.5. If necessary 1% Blocking reagent (w/v), dry milk powder, 1 to 5% heat inactivated fetal calf serum (v/v) or sheep normal serum can be used for reduction of unspecific binding.
Reconstitution
Add 1 ml double-distilled water to a final concentration of 150 U/ml.

Animals capable of adult regeneration require specific signaling to control injury-induced cell proliferation, specification and patterning, but comparatively little is known about how the regeneration blastema assembles differentiating cells into well-structured functional tissues. Using the planarian Schmidtea mediterranea as a

Pigmentation processes occur from invertebrates to mammals. Owing to the complexity of the pigmentary system, in vivo animal models for pigmentation study are limited. Planarians are capable of regenerating any missing part including the dark-brown pigments, providing a promising model

Zebrafish dorsal forerunner cells (DFCs) undergo vigorous proliferation during epiboly and then exit the cell cycle to generate Kupffer's vesicle (KV), a ciliated organ necessary for establishing left-right (L-R) asymmetry. DFC proliferation defects are often accompanied by impaired cilia elongation

Alternative polyadenylation (APA) is a widespread mechanism involving about half of the expressed genes, resulting in varying lengths of the 3' untranslated region (3'UTR). Variations in length and sequence of the 3'UTR may underlie changes of post-transcriptional processing, localization, miRNA
