Orexin Receptor 1 Blocking Peptide (#BLP-OR001) is the original antigen used for immunization during Anti-Orexin Receptor 1 Antibody (#AOR-001) generation. The blocking peptide binds and ‘blocks’ Anti-Orexin Receptor 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 OX1R in rat brainLongitudinal frozen section of rat brainstem showing staining (red) in neuronal cell bodies. Slides were incubated overnight at 4°C with Anti-Orexin Receptor 1 Antibody (#AOR-001), (1:50) followed by goat-anti-rabbit-AlexaFluor-555 secondary antibody (1:500). Hoechst 33342 is used as a counterstain (blue).
- Expression of OX1R in rat colonImmunohistochemical staining of paraffin-embedded longitudinal section of rat colon showing mucosa (M), submucosa (SM), and muscularis externa (ME) using Anti-Orexin Receptor 1 Antibody (#AOR-001), (1:100). Note that the stain (red-brown color) is highly specific for absorptive cells in the superior third of the intestinal glands. Immunolabeling was detected using DAB as the chromogen and hematoxilin as the counterstain.
- Expression of OX1R in mouse septumImmunohistochemical staining paraffin-fixed frozen sections using Anti-Orexin Receptor 1 Antibody (#AOR-001), (1:50). A. OX1R (green) appears in axonal processes (right-pointing triangles). B. Parvalbumin (red) appears in septal neurons. Cell nuclei (blue) are visualized with Hoechst 33342. C. Merge of OX1R and parvalbumin suggests that orexinergic innervation covers the entire septal nucleus rather than restricted to individual neurons.
