Intended Use:
Angiotensin-II EIA Kit (Human, Rat, Mouse or Canine)
is intended for in vitro quantitative study of Angiotensin-II amounts in any biological fluid, serum, plasma, tissue homogenate, urine and CSF.

Assay Principle:
1. Microwell plates have been pre-coated with secondary antibody and also the non-specific binding sites have been blocked.
2. Secondary antibody is able to bind with the Fc fragment of the primary antibody, the Fab segment is competitively bound by both biotinylated peptides and the peptide standard or the targeted peptide in samples.
3. Biotinylated peptide can then interact with the SA-HRP, which then catalyzes the TMB substrate solution and hydrogen peroxide to form a blue coloured solution.
4. Reaction is stopped by adding hydrogen chloride, which forms a yellow coloured solution.
5. Intensity of the yellow solution is inversely proportional to the amount of the peptide in standard solutions or samples.
6. Unknown concentration in samples can then be determined using this Angiotensin-II EIA assay by extrapolation from a standard curve.

Cross Reactivity:

Angiotensin III (Human)  100%.
[Val5]-Angiotensin II (Human)  100%.
Angiotensin II (1-7) (Human)  0%.
Angiotensin I (Human)  1%.
Angiotensin I (1-9) (Human)  1%.
Renin Substrate  0%.
Angiotensin (1-7)  0%.
α-ANP (1-28)  0%.
[Sar1, Ile8]-Angiotensin II  0%.
[Arg8]-Vasopressin 0%.

Human Angiotensin-II is found to act as an autocrine, paracrine, intracrine hormone and endocrine. It has prothrombotic potential by its aggregation and adhesion of platelets. Itcan also cause vascular and cardiac muscle hypertrophy.  Increase the thirst sensation through the subfornical organ of the brain. Has a direct effect on the proximal tubules to increase Naion resorption.
