Product Overview
This rabbit polyclonal antibody detects glial cell line-derived neurotrophic factor (gene GDNF) in human and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 23.7 kDa, and the supplier reports an observed band at about 17 kDa.
Glial cell line-derived neurotrophic factor (GDNF) is a secreted growth factor that strongly supports the survival of dopaminergic and motor neurons. It binds the coreceptor GFRα1 and signals through the RET tyrosine kinase. GDNF is also required for kidney development and spermatogonial stem cell maintenance, and it is studied in Parkinson's disease research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Rat) |
Samples with a confirmed band (WB): recombinant human GDNF protein.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 12% SDS-PAGE, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human stomach cancer tissue, human lung cancer tissue, rat brain tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide from the middle region of human GDNF. It differs from the mouse sequence at three residues.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt describes glial cell line-derived neurotrophic factor as a secreted protein. Tissue expression noted by UniProt (human): In the brain, predominantly expressed in the striatum with highest levels in the caudate and lowest in the putamen. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
