生物活性

Spadin, a natural peptide derived from a propeptide released in blood, is a potent TREK-1 channel blocker with IC50 value of 10 nM. Spadin enhances dorsal raphe nucleus 5-HT neurotransmission in mice and induces hippocampal CREB activation and neurogenesis. Spadin can be used for antidepressant research[1][2].

体外研究
(In Vitro)

Spadin (100 nM; COS-7 cells) has inhibitory effect of spadin on the TREK-1 channel and blocks 63% of the TREK-1 current stimulated by arachidonic acid[1].
Spadin (100 nM) blocks the TREK-1 channels activity in CA3 hippocampal neurons on brain slices of wild-type mice[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Spadin (10 μM; i.p.; for 30 min; male C57Bl/6J and TREK-1 deficient mice) increases of the 5-HT neuron firing rate in the dorsal raphe nucleus (DRN)[2].
Spadin (0.01-100 μM; ICV, i.p. and i.v.; daily, for 7 days; male C57Bl/6J and TREK-1 deficient mice) has anti-depressant behavior in mice[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male C57Bl/6J and TREK-1 deficient mice[2]
Dosage: 10 μM
Administration: Intraperitoneal injection; for 30 min
Result: Increased of the 5-HT neuron firing rate in the dorsal raphe nucleus (DRN).
Animal Model: Male C57Bl/6J and TREK-1 deficient mice[2]
Dosage: 0.01-100 μM
Administration: Intracerebroventrical injection, intraperitoneal injection and intravenous injection; daily, for 7 days
Result: Had any effect on mouse locomotion analyzed in short- or long-time after the drug injection.

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.
