PepT2/SLC15A2 (extracellular) Blocking Peptide (#BLP-PT002) is the original antigen used for immunization during Anti-PepT2/SLC15A2 (extracellular) Antibody (#APT-002) generation. The blocking peptide binds and ‘blocks’ Anti-PepT2/SLC15A2 (extracellular) 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 PepT2/SLC15A2 in rat subfornical organ.Immunohistochemical staining of perfusion-fixed frozen rat brain sections with Anti-PepT2/SLC15A2 (extracellular) Antibody (#APT-002), (1:100), followed by goat anti-rabbit-AlexaFluor-488. A. PepT2 immunoreactivity (green) appears in cells of the subfornical organ (arrows). B. Pre-incubation of the antibody with PepT2/SLC15A2 (extracellular) Blocking Peptide (BLP-PT002), suppressed staining. Cell nuclei are stained with DAPI (blue). FX = fornix.
