Presenilin-1 Blocking Peptide (#BLP-IP011) is the original antigen used for immunization during Anti-Presenilin-1 Antibody (#AIP-011) generation. The blocking peptide binds and ‘blocks’ Anti-Presenilin-1 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.

- Expression of Presenilin-1 in mouse brainImmunohistochemical staining of mouse hippocampus and mouse cerebellum using Anti-Presenilin-1 Antibody (#AIP-011), (1:600). A. In hippocampus, PS-1 staining (green) appears in apical dendrites of pyramidal neurons (arrows). B. In cerebellum, an intense staining for PS-1 (green) appears in dendritic trees of Purkinje cells (arrows). A moderate staining is detected in the granule layer and in the soma of Purkinje and molecular layer interneurons. In both panels DAPI is used as the counterstain.
