Used in neuroscience and pharmacological research to quantify serotonin receptor 3 (5-HTR3) levels in mouse tissue samples, particularly in brain and gastrointestinal studies. Enables researchers to investigate the role of 5-HTR3 in mood regulation, nausea, vomiting, pain perception, and gut motility. Commonly applied in drug development to assess the impact of experimental compounds on receptor expression. Supports studies on psychiatric disorders, irritable bowel syndrome, and antiemetic therapies by providing a reliable method to measure receptor concentration in experimental models.
