Used in neuroscience and cannabinoid research to detect and quantify CB1 receptors in brain tissue and cell cultures. Enables study of receptor distribution, expression changes in disease models, and effects of drug treatments. Commonly applied in Western blotting, immunohistochemistry, and flow cytometry. Supports investigation into neurological disorders such as epilepsy, chronic pain, and addiction. Also used in pharmacological studies to evaluate receptor modulation by therapeutic compounds.
