Biological Activity
Parstatin (0-10 µM) increases recovery of LVDP in a concentration-dependent manner. The optimal concentration was 1 µM which produced a 23% recovery of LVDP[2].

Animal Model:Male Sprague–Dawley rats at 8 weeks of age (250-300 g)[1].
-
Dosage:1-25 µg/kg.
-
Administration:IV injected 15 min prior to ischaemia.
-
Result:A significant decrease in infarct size was detected with the 5-15 µg/kg doses with 10 µg/kg as the optimal dose. These hearts had an infarct size of 46 ± 3% of the area at risk, which is a 26% reduction in infarct size compared with the control.

Solvent & Solubility

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. |
