AP102
AP102 is a dual SSTR2/SSTR5-specific somatostatin analog (SSA). AP102 is a disulfide-bridged octapeptide SSA containing synthetic iodinated amino acids. AP102 binds with subnanomolar affinity to SSTR2 and SSTR5 (IC50: 0.63 and 0.65 nM, respectively). AP102 does not bind to SSTR1 or SSTR3. AP102 can be used for acromegaly and neuroendocrine tumors research.

Biological Activity
|
SSTR2 0.63 nM (IC50) |
SSTR5 0.65 nM (IC50) |
AP102 inhibits GHRH-stimulated GH release and prolactin release from rat anterior pituitary cells in vitro. The IC50 levels for GH and prolactin inhibition were low (0.15 and 0.23 nM, respectively) and were similar to those obtained with somatostatin 14 (0.1 and 0.2 nM, respectively)[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:
| 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. |
