Used in biomedical research to quantify rat somatostatin receptor 2 (SSTR2) levels in tissue extracts, cell lysates, or biological fluids. Enables investigation of SSTR2 expression in neuroendocrine studies, cancer research, and drug development involving somatostatin signaling pathways. Supports evaluation of receptor modulation in response to therapeutic agents or disease states in rodent models. Provides a reliable, sensitive, and specific method for high-throughput screening in preclinical studies.
