CCK-8, Sulfated

Sulfated CCK-8 is the biologically potent C-terminal octapeptide of cholecystokinin. Tyrosine sulfation is critical for high-affinity CCK1 receptor activity, making this exact modified peptide important for gastrointestinal, satiety and receptor-pharmacology studies.

• peptide hormone and GPCR research
• neuroendocrine signaling
• metabolic or renal physiology
• receptor and structure-activity studies

Disulfide connectivity, phosphorylation, sulfation, amidation and affinity labels are integral to exact product identity and should be preserved in comparative assays.
