GABARAP Blocking Peptide (#BLP-IP016) is the original antigen used for immunization during Anti-GABARAP Antibody (#AIP-016) generation. The blocking peptide binds and ‘blocks’ Anti-GABARAP 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.
- Western blot analysis of mouse brain (lanes 1 and 4), rat brain (lanes 2 and 5) and human neuroblastoma (SH-SY5Y) cell line (lanes 3 and 6) lysates:
- Expression of GABARAP in rat cortex.Immunohistochemical staining of perfusion-fixed frozen rat brain sections with Anti-GABARAP Antibody (#AIP-016), (1:1000), followed by donkey anti-rabbit-biotin and Streptavidin-Cy3. A. GABARAP immunoreactivity (red) appears in cortical neurons (arrows). B. Pre-incubation of the antibody with GABARAP Blocking Peptide (#BLP-IP016), suppressed staining. Cell nuclei are stained with DAPI (blue).
