Potent endogenous vasoconstrictor peptide; derivative of angiotensin (Ang) II. Elicits pressor and renal vasoconstrictor effects in rodents via the AT1 receptor; inhibited by Candesartan (Cat. No. 4791) but not by AT2 receptor ligands in vivo. Displays a similar affinity for AT1 and AT2 receptors as angiotensin II in vitro (Ki values are 1.6 and 2.3 nM at AT1 and AT2 receptors); also increases inositol phosphate accumulation with a similar potency to Ang II (EC50 = 6.7 nM).

Preparing Stock Solutions
The following data is based on the product molecular weight 1002.18. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||1 mL||4.99 mL||9.98 mL|
|5 mM||0.2 mL||1 mL||2 mL|
|10 mM||0.1 mL||0.5 mL||1 mL|
|50 mM||0.02 mL||0.1 mL||0.2 mL|
