Sigma-1 Receptor Blocking Peptide (#BLP-IP006) is the original antigen used for immunization during Anti-Sigma-1 Receptor Antibody (#AIP-006) generation. The blocking peptide binds and ‘blocks’ Anti-Sigma-1 Receptor 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 Sigma-1 Receptor in rat spinal cord.Immunohistochemical staining of perfusion-fixed frozen rat spinal cord sections with Anti-Sigma-1 Receptor Antibody (#AIP-006), (1:300), followed by goat anti-rabbit-AlexaFluor-488. A. Sigma-1 Receptor immunoreactivity (green) appeared in the superficial layer of the dorsal horn (arrows). B. Pre-incubation of the antibody with Sigma-1 Receptor Blocking Peptide (BLP-IP006), suppressed staining. Cell nuclei are stained with DAPI (blue).
