Overview
Type: Synthetic peptide
Form: Lyophilized powder
GDNF Blocking Peptide (#BLP-NT014) is the original antigen used for immunization during Anti-GDNF Antibody (#ANT-014) generation. The blocking peptide binds and ‘blocks’ Anti-GDNF primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.
Applications: wb, ihc
For research purposes only. not for human use
Applications
Demonstration of Pre-adsorption control
Western blot analysis of Recombinant human GDNF protein:Lanes 1, 4: 50 ng Recombinant human GDNF protein (#G-240).
Lanes 2, 5: 10 ng Recombinant human GDNF protein.
Lanes 3, 4: 1 ng Recombinant human GDNF protein.
Lanes 1-3: Anti-GDNF Antibody (#ANT-014), (1:1000).
Lanes 4-5: Anti-GDNF Antibody, preincubated with GDNF Blocking Peptide (#BLP-NT014).
Expression of GDNF in rat dorsal root ganglion (DRG).Immunohistochemical staining of rat DRG longitudinal frozen section using Anti-GDNF Antibody (#ANT-014), (1:50), followed by Alexa 555-conjugated goat anti-rabbit antibody (red). Hoechst 33342 (blue) was used as a counterstain. GDNF staining is specific for neurons. Note that Schwann cells as well as satellite glial cells are both negative.
Expression of GDNF in rat hippocampusImmunohistochemical staining of rat hippocampus frozen sections with Anti-GDNF Antibody (#ANT-014), (1:100), (red). A. GDNF staining is apparent in the pyramidal layer (asterik), in astrocytic fibers (horizontal arrows) and in some interneurons (vertical arrow). B. Calbindin D28k (green) appears in a subset of cells in the pyramidal layer. C. Merge of GDNF and calbindin demonstrates some co-localization in neurons. DAPI is used as the counterstain (blue).
