Angiotensin I/II (1-6) TFA contains the amino acids 1-6 and is converted from Angiotensin I/II peptide. The precursor angiotensinogen is cleaved by renin to form angiotensin I. Angiotensin I ishydrolyzed by angiotensin-converting enzyme (ACE) to form the biologically active angiotensin II. Angiotensin II has been investigated for the treatment, basic science, and diagnostic of Hypertension, Renin Angiotensin System, and Idiopathic Membranous Nephropathy[1][2][3].

(In Vitro)

Angiotensin II is a naturally occurring octapeptide hormone component of the renin-angiotensin-aldosterone system (RAAS) and is a potent vasoconstrictor. Angiotensin II has important roles in cardiovascular, neurologic, and renal physiology, including maintenance of blood pressure, thirst sensation, response to the baroreceptor reflex, determination of renal blood flow and glomerular filtration rate, and electrolyte and free water homeostasis[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Peptide Solubility and Storage Guidelines:

1.;;Calculate the length of the peptide.

2.;;Calculate the overall charge of the entire peptide according to the following table:

; Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.;;Recommended solution:

Overall charge of peptide Details
Negative (lt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, add NH4OH (lt;50 μL).
3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.;;If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0) 1.;;Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.;;For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
