生物活性

OSK-1 is a potent Kv channel blocker with IC50s of of 0.6 nM, 5.4 nM, 0.014 nM for Kv1.1, Kv1.2 and Kv1.3, respectively. OSK1 is a moderate blocker of Ca2+-activated KCa3.1 channel with an IC50 of 225 nM. OSK-1 belongs to α-KTx3 toxins and is used as a immunosuppressive agent[1].

IC50 & Target

IC50: 0.6 nM (Kv1.1), 5.4 nM (Kv1.2), 0.014 nM (Kv1.3) and 225 nM (KCa3.1)[1]
体外研究
(In Vitro)

OSK1 has no effect on KCa2.1, KCa2.2, KCa2.3 and KCa1.1 channels when in the micromolar concentration range, whereas it shows a moderate activity on KCa3.1 channel (also referred to as IK1 or SK4) with an IC50 value of 225 nM[1].

MCE 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.

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.
