Used in biomedical research to measure substance P levels in biological samples such as plasma, serum, or tissue homogenates. Substance P is a neuropeptide involved in pain transmission, inflammation, and neurogenic responses. This ELISA kit enables researchers to quantify substance P in studies related to neurological disorders, chronic pain, depression, migraine, and inflammatory diseases. It is widely applied in preclinical studies using animal models, including canine research, to evaluate neuroimmune interactions and the effectiveness of therapeutic compounds targeting the nervous system. The kit provides a sensitive and specific method for detecting changes in substance P concentration in response to stimuli or treatment.
