Angiotensin II, Phospho-Tyr4

This Angiotensin II analog contains phosphotyrosine at residue 4. The added phosphate changes charge and recognition properties and has been used as a defined phosphopeptide substrate/reference in biochemical and mass-spectrometry studies.

• renin-angiotensin system research
• cardiovascular and GPCR signaling
• ACE/chymase pathway studies
• mass spectrometry or affinity assays

Exact peptide length, isotope labeling, phosphorylation and affinity tags are integral to product identity. Use matched unlabeled or unmodified controls when comparing biological or analytical behavior.
