Description

Contulakin G is an O-glycosylated invertebrate neurotensin. Contulakin-G is a weaker agonist for the neurotensin receptor. Contulakin G is also a potent antinociceptive agent[1][2].

In Vivo

Contulakin G exhibits potent analgesic activity in three pain models in rats following intrathecal delivery, namely in tail-flick (acute pain), formalin test, and CFA-induced allodynia inflammatory pain[1].
Contulakin G (0-3 nmoL, Intrathecally) significantly decreases flinching behavior in rats[2].
Contulakin G (50-500 nmoL, Intrathecally) produces a dose-dependent increase in the thermally evoked skin twitch latency by 30 min after administration in dogs[2].

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

Animal Model: Male Holtzman rats (300-375 g)[2]
Dosage: 0.03, 0.1, 0.3, and 3 nmol
Administration: Intrathecally, administered as a 10-μL bolus followed by a 10-μL saline flush
Result: Produced a significant decrease in flinching in all phases of the formalin test in rats.
Animal Model: Purpose-bred beagle dogs (9-12 kg)[2]
Dosage: 50, 150, or 500 nmol
Administration: Intrathecally
Result: Produced a dose-dependent increase in the thermally evoked skin twitch latency at 30 min after dosing in dogs, which reached statistical difference as compared to vehicle at 500 nmol.

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.
