Features:The green fluorescent neuropeptide probe involves transplanting the fluorescence reporter module ICL3 from an existing neurotransmitter probe into another GPCR. It has high sensitivity and nanomolar-level sensitivity for detecting specific neuropeptides, such as Somatostatin (SST), Corticotropin-Releasing Factor (CRF), Cholecystokinin (CCK), Neuropeptide Y (NPY), Neuropeptide S (NPS), and Vasoactive Intestinal Peptide (VIP).
