Aquaporin-2 (254-267), pSer261, Human

This human AQP2 C-terminal fragment is phosphorylated at Ser261, a vasopressin-regulated site implicated in collecting-duct water-channel trafficking. It provides a defined phosphopeptide for phosphorylation-specific antibody, signaling and proteomic 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.
