产品使用指南

摩尔计算器

Jingzhaotoxin-III 是一种有效的、选择性 Nav1.5 通道阻滞剂，IC50 值为 348 nM，对其他钠通道亚型没有影响。Jingzhaoxin-III 可以选择性抑制心脏钠通道的激活，但不能抑制神经元亚型，有望成为区分心脏 VGSC 亚型的重要配体。

生物活性

Jingzhaotoxin-III is a potent and selective blocker of Nav1.5 channels, with an IC50 of 348 nM, and shows no effect on other sodium channel isoforms. Jingzhaotoxin-III can selectively inhibit the activation of cardiac sodium channel but not neuronal subtypes, and hopefully represents an important ligand for discriminating cardiac VGSC subtype[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:

  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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
