产品介绍
Big Endothelin-1 (1-39), porcine 是内皮素-1 (endothelin-1) 的前体。Endothelin-1 (ET-1) 是一种有效的升压肽。Big Endothelin-1 (1-39), porcine 在体内具有类似的升压作用。
生物活性

Big Endothelin-1 (1-39), porcine is the precursor of endothelin-1. Endothelin-1 (ET-1) is a potent vasopressor peptide. Big Endothelin-1 (1-39), porcine has similar pressor effects in vivo[1].

体外研究
(In Vitro)

Endothelin-1 (ET-1) is a potent, endothelial cell-derived, 21-amino acid peptide that has potent vasoconstricting properties and may participate in the regulation of blood pressure and regional blood flow[1].

体内研究
(In Vivo)

Big Endothelin-1 (1-39), porcine, the cDNA deduced putative precursor of ET-1, has been reported to have similar pressor effects in vivo[1].

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:

 ContentsAssign value
Acidic amino acidAsp (D), Glu (E), and the C-terminal -COOH.-1
Basic amino acidArg (R), Lys (K), His (H), and the N-terminal -NH2+1
Neutral amino acidGly (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 peptideDetails
Negative (<0)1.  Try to dissolve the peptide in water first.
2.  If water fails, add NH4OH (<50 μL).
3.  If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>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.
