| 生物活性 |
Antagonist G TFA is a potent vasopressin antagonist. Antagonist G is also a weak antagonist of GRP and Bradykinin. Antagonist G induces AP-1 transcription and sensitizes cells to chemotherapy[1][2].

体外研究
(In Vitro) |
Antagonist G (0-100 μM) induces apoptosis is redox-sensitive and caspase-dependently in SCLC cells[2].
Antagonist G activates JNK1 in SCLC cells[2].
Antagonist G is not intrinsically a free radical oxygen donor but stimulates free radical generation specifically within SCLC cells (6.2-fold) and increases the activity of the redox-sensitive transcription factor AP-1 by 61%[2].
上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

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. |
