Used in biomedical research to measure somatostatin levels in biological samples such as serum, plasma, and tissue homogenates. Helps in studying neuroendocrine function, pancreatic hormone regulation, and neurotransmission. Commonly applied in research on diseases like acromegaly, diabetes, and certain neurological disorders where somatostatin signaling is altered. Supports high-throughput screening and quantitative analysis in preclinical studies.
