Overview
Type: Synthetic peptide
Form: Lyophilized powder
Cannabinoid Receptor 1 (extracellular) Blocking Peptide (#BLP-CR001) is the original antigen used for immunization during Anti-Cannabinoid Receptor 1 (extracellular) Antibody (#ACR-001) generation. The blocking peptide binds and ‘blocks’ Anti-Cannabinoid Receptor 1 (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.
Applications: wb, ihc

Applications
Demonstration of Pre-adsorption control
Western blot analysis of rat brain membrane proteins:1. Anti-Cannabinoid Receptor 1 (extracellular) Antibody (#ACR-001), (1:200).
2. Anti-Cannabinoid Receptor 1 (extracellular) Antibody, preincubated with Cannabinoid Receptor 1 (extracellular) Blocking Peptide (#BLP-CR001).
Expression of CB1 receptor in mouse hippocampusImmunohistochemical staining of mouse hippocampus using Anti-Cannabinoid Receptor 1 (extracellular) Antibody (#ACR-001), (1:100). A. CB1 is detected in pyramidal and infra-pyramidal layers (green). B. Staining of interneurons using mouse anti-parvalbumin (PV) antibody (red). C. Confocal merge of A and B does not indicate the presence of CB1 in GABAergic cells.- Expression of CB1 receptor in rat hippocampusImmunohistochemical staining of rat hippocampus using Anti-Cannabinoid Receptor 1 (extracellular) Antibody (#ACR-001) (1:100). A. CB1 is detected in pyramidal and infra-pyramidal layers (green). B. Staining of interneurons using mouse anti-parvalbumin (PV) antibody (red). C. Confocal merge of A and B does not indicate the presence of CB1 in GABAergic cells.
Western blot analysis of mouse brain lysates (lanes 1 and 3) and rat brain membranes (lanes 2 and 4):1-2. Guinea Pig Anti-Cannabinoid Receptor 1 (extracellular) Antibody (#ACR-001-GP), (1:400).
3-4. Guinea Pig Anti-Cannabinoid Receptor 1 (extracellular) Antibody (#ACR-001-GP), preincubated with Cannabinoid Receptor 1 (extracellular) Blocking Peptide (#BLP-CR001).
Expression of Cannabinoid Receptor 1 in mouse hippocampus.Immunohistochemical staining of perfusion-fixed frozen mouse brain sections with Guinea Pig Anti-Cannabinoid Receptor 1 (extracellular) Antibody (#ACR-001-GP), (1:200), followed by goat anti-guinea pig - Alexa Fluor-594. A. Staining in the dentate gyrus region, showed CB1R immunoreactivity (red) in axonal outlines in the outer molecular layer (arrows pointing down) and in the hilus (arrows pointing up). B. Pre-incubation of the antibody with Cannabinoid Receptor 1 (extracellular) Blocking Peptide (#BLP-CR001), suppressed staining. Cell nuclei are stained with DAPI (blue). G = granule layer, H = hilus.
