Nelipepimut-S
Nelipepimut-S (E75) is a peptide vaccine targeting HER2. When used in combination with granulocyte-macrophage colony-stimulating factor, Nelipepimut-S stimulates immune activity and induces anti-HER2 immune responses. Nelipepimut-S can be used in research related to breast cancer, triple-negative breast cancer and ductal carcinoma in situ.

HER2 |
Nelipepimut-S acts as the HLA-A2 immunodominant epitope of HER2, potently stimulating cell lysis by ovarian cancer reactive CTL lines and demonstrating high HLA-A2 stabilizing ability[2].
Nelipepimut-S is presented on HLA-A2 in ovarian cancer cell lines and is recognized by ovarian cancer-associated CD8+ T-cell clones[2].

Solvant et solubilité
H2O
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. |
