Description

Dermorphin TFA is a natural heptapeptide μ-opioid receptor (MOR) agonist found in amphibian skin. Inhibition of neuropathic pain^[1].

IC₅₀ & Target

μ Opioid Receptor/MOR

In Vitro

Dermorphin, a peptide isolated from the skin of Phyllomedusa frogs and the peptide receptor (NOP) component by the endogenous agonist nociceptin/orphanin FQ (N/OFQ). In displacement binding studies at CHO_hMu, Dermorphin and DeNo displac the binding of [³H]-DPN in a concentration dependent and saturable manner. Dermorphin displays an affinity of 7.17, while N/OFQ fails to displace [³H]-DPN at the Delta receptor. Dermorphin and DeNo stimulate the binding of GTPγ[³⁵S] in a concentration dependent and saturable manner at the Mu receptor^[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.
