Overview
Type: Synthetic peptide
Form: Lyophilized powder
Vesicular GABA Transporter/VGAT Blocking Peptide (#BLP-GT005) is the original antigen used for immunization during Anti-Vesicular GABA Transporter (VGAT) Antibody (#AGT-005) generation. The blocking peptide binds and ‘blocks’ Anti-Vesicular GABA Transporter/VGAT 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
Demonstration of Pre-adsorption control
Western blot analysis of rat brain membranes (lanes 1 and 4), mouse brain membranes (lanes 2 and 5) and human U-87 MG glyoblastoma lysates (lanes 3 and 6):1-3. Anti-Vesicular GABA Transporter (VGAT) Antibody (#AGT-005), (1:200).
4-6. Anti-Vesicular GABA Transporter (VGAT) Antibody, preincubated with Vesicular GABA Transporter/VGAT Blocking Peptide (#BLP-GT005).
Expression of Vesicular GABA Transporter in rat cerebellumImmunohistochemical staining of rat frozen cerebellum sections using Anti-Vesicular GABA Transporter (VGAT) Antibody (#AGT-005), (1:100). VGAT staining is shown in red and dapi (blue) was used as a general cellular marker. VGAT appears in the cerebellar pinceau (arrows) and in the soma of Purkinje cells (triangles).

Guinea pig Anti-Vesicular GABA Transporter (VGAT) Antibody (#AGT-005-GP), (1:200).
5-8. Guinea pig Anti-Vesicular GABA Transporter (VGAT) Antibody, preincubated with Vesicular GABA Transporter/VGAT Blocking Peptide (#BLP-GT005).
Expression of VGAT in mouse cerebellum.Immunohistochemical staining of perfusion-fixed frozen mouse brain sections with Guinea pig Anti-Vesicular GABA Transporter (VGAT) Antibody (#AGT-005-GP), (1:600), followed by goat anti-guinea pig-AlexaFluor-594. A. VGAT immunoreactivity (red) appears in the granule layer (GL) and in “pinceau” structures adjacent to purkinje cells (arrows). B. Pre-incubation of the antibody with Vesicular GABA Transporter/VGAT Blocking Peptide (#BLP-GT005), suppressed staining. Cell nuclei are stained with DAPI (blue).- Expression of VGAT in rat cerebellum.Immunohistochemical staining of perfusion-fixed frozen rat brain sections with Guinea pig Anti-Vesicular GABA Transporter (VGAT) Antibody (#AGT-005-GP), (1:600), followed by goat anti-guinea pig-AlexaFluor-594.
