Anti-Angiotensin I antibody (ab8051)


  • Product name
    Anti-Angiotensin I antibody
    See all Angiotensin I primary antibodies
  • Description
    Rabbit polyclonal to Angiotensin I
  • Specificity
    Specificity of the antisera is confirmed by its ability to bind and precipitate labeled angiotensin I and to be adsorbed by angiotensin. Native angiotensin competes with such binding, while human whole plasma or plasma proteins do not. The antiserum also reacts with angiotensin II (Reactivity in competitive ELISA was shown : 80% to Angiotensin II; 100% to Angiotensin I)
  • Tested applications
    Suitable for: ELISAmore details
    Unsuitable for: IHC
  • Species reactivity
    Reacts with: Human
    Predicted to work with: Mouse, Rat, Dog
  • Immunogen

    Synthetic peptide:


    conjugated to BSA by a CDI linker, corresponding to N terminal amino acids 34-43 of Human Angiotensin I.

  • General notes
    The enzyme renin cleaves angiotensinogen to produce an inactive prohormone, angiotensin I; the latter is transformed to the active molecule angiotensin II by another enzyme, angiotensin-converting enzyme



Our Abpromise guarantee covers the use of ab8051 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Target

    • Function
      Essential component of the renin-angiotensin system (RAS), a potent regulator of blood pressure, body fluid and electrolyte homeostasis. In response to lowered blood pressure, the enzyme renin cleaves angiotensinogen to produce angiotensin-1 (angiotensin 1-10). Angiotensin-1 is a substrate of ACE (angiotensin converting enzyme) that removes a dipeptide to yield the physiologically active peptide angiotensin-2 (angiotensin 1-8). Angiotensin-1 and angiotensin-2 can be further processed to generate angiotensin-3 (angiotensin 2-8), angiotensin-4 (angiotensin 3-8). Angiotensin 1-7 is cleaved from angiotensin-2 by ACE2 or from angiotensin-1 by MME (neprilysin). Angiotensin 1-9 is cleaved from angiotensin-1 by ACE2.
      Angiotensin-2 acts directly on vascular smooth muscle as a potent vasoconstrictor, affects cardiac contractility and heart rate through its action on the sympathetic nervous system, and alters renal sodium and water absorption through its ability to stimulate the zona glomerulosa cells of the adrenal cortex to synthesize and secrete aldosterone.
      Angiotensin-3 stimulates aldosterone release.
      Angiotensin 1-7 is a ligand for the G-protein coupled receptor MAS1 (By similarity). Has vasodilator and antidiuretic effects (By similarity). Has an antithrombotic effect that involves MAS1-mediated release of nitric oxide from platelets.
    • Tissue specificity
      Expressed by the liver and secreted in plasma.
    • Involvement in disease
      Genetic variations in AGT are a cause of susceptibility to essential hypertension (EHT) [MIM:145500]. Essential hypertension is a condition in which blood pressure is consistently higher than normal with no identifiable cause.
      Defects in AGT are a cause of renal tubular dysgenesis (RTD) [MIM:267430]. RTD is an autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype).
    • Sequence similarities
      Belongs to the serpin family.
    • Post-translational
      Beta-decarboxylation of Asp-34 in angiotensin-2, by mononuclear leukocytes produces alanine. The resulting peptide form, angiotensin-A, has the same affinity for the AT1 receptor as angiotensin-2, but a higher affinity for the AT2 receptor.
