[Pro9]-Substance P 是一种有效的、可逆的、选择性的NK-1速激肽受体激动剂,其EC50为 0.93 nM。
生物活性 | [Pro9]-Substance P is a potent, reversible and selective agonist ofNK-1tachykinin receptors with anEC50of 0.93 nM[1]. |
IC50& Target[1] | |
体外研究 (In Vitro) | [3H][Pro9]-Substance P can be used as a radio ligand for NK- 1 binding sites[1]. [Pro9]-Substance P stimulates inositol phosphate formation with an efficacy only slightly lower than that of SP (EC50values of 0.93 ± 0.07 and 0.45 ± 0.06 nM, respectively) on primary cultures of newborn mouse cortical glial cells[1].

Solvent & Solubility | In Vitro: 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. |
