| 生物活性 |
Guanylin(human), a 15-amino acid peptide, is an endogenous intestinal guanylate cyclase activator. Guanylin(human) is mainly found in gastrointestinal tract which regulates electrolytead water transport in intestinal and renal epithelia through cyclic GMP-dependent mechanism[1][2].

| 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) |

| 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. |
