产品介绍
Huwentoxin-IV 是一种有效的、选择性钠通道阻滞剂,可抑制神经元Nav1.7Nav1.2Nav1.3Nav1.4IC50值分别为 26、150、338 和 400 nM。Huwentoxin-IV 通过结合神经毒素受体位点 4 优先阻断周围神经 Nav1.7 亚型。Huwentoxin-IV 可用于炎性和神经性疼痛的动物模型的研究。
生物活性

Huwentoxin-IV is a potent and selectivesodium channelblocker, inhibits neuronalNav1.7,Nav1.2,Nav1.3andNav1.4withIC50s of 26, 150, 338 and 400 nM, respectively. Huwentoxin-IV preferentially blocks peripheral nerve subtype Nav1.7 by binding neurotoxin receptor site 4. Huwentoxin-IV has analgesic effects on animal models of inflammatory and neuropathic pain[1][2].

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:

 ContentsAssign value
Acidic amino acidAsp (D), Glu (E), and the C-terminal -COOH.-1
Basic amino acidArg (R), Lys (K), His (H), and the N-terminal -NH2+1
Neutral amino acidGly (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 peptideDetails
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.
