Somatostatin receptors are a subfamily of GPCRs and include five members. They are widely distributed throughout the central and peripheral nervous system and can bind endogenous somatostatin with a high affinity. The activation of somatostatin receptors triggers various signaling pathways, which are related to multiple crucial physiological activities such as the suppression of GH secretion and the regulation of neural activity. Consequently, it has immense importance for comprehensive investigations of somatostatin receptors.

In an attempt to help in the discovery of pharmaceuticals for the treatment of diseases, Creative Biolabs succeeded in developing a speedy and steady Magic™ in vitro cell-based somatostatin receptor functional assay service, which is currently offered to customers throughout the world.
The activation of somatostatin receptors triggers an array of cellular reactions to transduce the signals. Accordingly, we utilize the variation of second messengers or ion fluxes caused by the treatment of samples as the indicator of our Magic™ in vitro cell-based somatostatin receptor functional assay service. Also, we can examine the fluorescent intensity to detect the receptor internalization. At Creative Biolabs, the incorporation of our professional team and top-ranking services will enable the desirable outcomes for every customer at a rapid turnover.

Representative data 1: All five somatostatin receptors (SSTR1-5) may be activated by the endogenous cyclic tetradecapeptide SST14, leading to increased hormone production, improved neurotransmission, halted cell development, and reduced cancer risk. Researchers have created two short cyclic SST analogs that selectively activate SSTR2 to treat acromegalia and neuroendocrine tumors. Based on a structural analysis of the human SSTR2-Gi complex in the presence of SST14 and two short cyclic SST analogs, this study uncovered the critical site for receptor binding and functional stimulation of the two SST14-derived cyclic octapeptides, providing useful information for the design of SST analog drugs that target SSTR.
