Somatostatin （also known as growth hormone inhibiting hormone （GHIH） or somatotropin release-inhibiting hormone （SRIF） is a peptide hormone that regulates the endocrine systemand affects neurotransmission and cell proliferation via interaction with G-protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin has two active forms produced by alternative cleavage of a single preproprotein: one of 14 amino acids， the other of 28 amino acids.
Lyophilized SST although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution Somatostatin should be stored at 4℃ between 2-7 days and for future use below -18℃.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles.
