| Product name | Angiotensin Ⅱ human, FAM‑labeled |
| Description | This fluorescent peptide is a labeled tool peptide obtained by site‑specific conjugation of FAM fluorescent group at the N‑terminus of human angiotensin Ⅱ. It fully retains the binding activity of native angiotensin Ⅱ to AT1 and AT2 receptors, and can be quantitatively detected via the green fluorescence signal of FAM. It is widely used in research scenarios such as angiotensin receptor affinity determination, receptor binding competition assay, cell receptor endocytosis imaging, and high‑throughput screening of hypertension drugs. It is a classic fluorescent tool for the study of renin‑angiotensin system. |

| PEP-ANGF001 | Green fluorescent labeled angiotensin Ⅱ probe that retains receptor binding activity, for receptor binding and imaging research | This labeled peptide retains the complete amino acid sequence and receptor binding activity of native angiotensin Ⅱ. It can specifically bind AT1 and AT2 receptors on the surface of tissue cells such as vascular smooth muscle, myocardium and kidney, while emitting stable green fluorescence via the N-terminal conjugated FAM group. It can be used in various experimental scenarios such as receptor-ligand affinity determination, competitive binding assay for screening receptor antagonists, live cell receptor tracing and endocytosis imaging, and flow cytometry quantification of receptor expression. It is a classic fluorescent tool for pharmacological research of renin-angiotensin system. | Hypertension mechanism research, AT receptor pharmacology, Receptor binding assay, Cell fluorescence imaging, High-throughput drug screening, Fluorescent tool peptide | Angiotensin AT1/AT2 receptors; FAM fluorescence tracing; Receptor-ligand interaction pathway |
