| Targets |
This short N-terminal fragment lacks the C-terminal residues required for high-affinity binding to AT1 or AT2 receptors. It is not an active receptor ligand but may interact nonspecifically or serve as an ACE substrate.
|
|---|---|
| ln Vitro |
As a short peptide fragment, it does not exhibit significant receptor binding activity or functional signaling in standard cell-based assays. It may be used to study enzymatic cleavage patterns or as a peptide stability control.
|
| ln Vivo |
This peptide lacks intrinsic vasoactive properties. It is inactive in blood pressure regulation models and does not produce the classic effects of angiotensin II, such as vasoconstriction or aldosterone release.
|
| Enzyme Assay |
Receptor binding studies typically use membrane preparations from tissues or cells expressing AT1 or AT2 receptors, incubated with radiolabeled angiotensin II. This peptide serves as a control to demonstrate binding specificity. Enzyme assays with ACE can measure its cleavage.
|
| Cell Assay |
The peptide can be added to cell cultures expressing ACE to monitor enzymatic conversion to smaller fragments via HPLC or mass spectrometry. It is not typically used for functional readouts like calcium flux or cAMP accumulation.
|
| Animal Protocol |
In animal models, this peptide is primarily administered for pharmacokinetic studies to track peptide metabolism and degradation. Blood samples are collected at various time points and analyzed by LC-MS/MS to quantify the peptide and its metabolites.
|
| ADME/Pharmacokinetics |
Like other small peptides, it is rapidly degraded by peptidases in plasma and tissues, resulting in a very short half-life (likely less than a few minutes). It is cleared primarily via hydrolysis and renal excretion.
|
| Toxicity/Toxicokinetics |
No significant toxicity is reported for this peptide fragment in standard research applications. It exhibits low biological activity and is considered safe when handled according to standard laboratory safety protocols for peptides.

| Additional Infomation |
This peptide is a minimal fragment of the angiotensin II sequence and is often used as a negative control or metabolite marker in experiments involving the RAAS. It is not intended for clinical use. Strictly a research-grade biochemical.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

| 5 mM | 0.2568 mL | 1.2841 mL | 2.5682 mL | |
| 10 mM | 0.1284 mL | 0.6420 mL | 1.2841 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
