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 (<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. |
Protocol
Rats[2]
Experiments are performed on male Wistar rats (n = 100) weighing 250-280 g. The animals are divided into groups (10 specimens per group). They are maintained under standard vivarium conditions and have free access to water and food (12:12-h light/dark regimen). δ-Sleep Inducing Peptide is dissolved in physiological saline and injected intraperitoneally 60 min before each stress exposure. Control animals receive an equivalent volume of physiological saline (1 mL/kg). The liver is homogenized in ice-cold physiological saline and centrifuged. The content of LPO products and activities of antioxidant enzymes are measured in the supernatant. LPO intensity is evaluated by malonic dialdehyde (MDA) concentration. Activities of superoxide dismutase (SOD) and catalase are measured spectrophotometrically. The total antioxidant activity (TAA) is evaluated by the method based on inhibition of ascorbate-induced and iron-induced oxidation of Tween-80 to MDA. The assay is conducted on a BTS-330 biochemical analyzer[2].
