Cortistatin 17, human

Cortistatin 17, human is a synthetic research peptide in the cortistatin peptide family. Cortistatin is structurally related to somatostatin and binds with high affinity to all five somatostatin receptor subtypes. Cortistatin peptides are used to compare somatostatin-receptor pharmacology and to investigate cortistatin-specific neuroendocrine and immune signaling.

• somatostatin receptor binding assays
• cortistatin versus somatostatin comparisons
• neuroendocrine signaling studies

The exact sequence, residue range, species, terminal state, and chemical modifications should be matched to the intended assay. Fragmentation or processing can materially alter receptor selectivity, potency, aggregation, or enzymatic behavior.
