生物活性

Eledoisin Related Peptide is a Substance P analog that excites neurons and triggers behavioral responses. Eledoisin Related Peptide is also a tachykinin receptor ligand.

IC50 Target

Tachykinin receptor[1]
体内研究
(In Vivo)

Eledoisin Related Peptide shares with Substance P (SP) a common N-terminal amino acid sequence and has been shown by to have SP-like activity in the periphery (gut and salivary glands) and the CNS. Eledoisin-related peptide seems to be roughly equipotent with Substance P at identical ejection currents on the single-cell activity of neurons in this nucleus[2]. Both glutamate and substance P (and its analogue, eledoisin-related peptide) have excitatory effects on the activity of respiratory neurons and reflex interneurons[3].

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 (lt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, add NH4OH (lt;50 μL).
3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;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.

Rats[2]

Twenty-two male albino rats (230-260 g) are anesthetized with chloral hydrate (400 mg/kg, i.p.) and prepared for recording. Briefly, a singlebarrel recording pipette (tip 1 μm) is glued alongside a conventional five-barrel micropipette (tip 15-25/μm) then filled with 2 M NaCI saturated with Fast Green (impedance 4-7 M). The distance between the tip of the recording electrode and that of the five-barrel micropipette is 15-25/zm. Fast Green is ejected at the end of the experiment to identify the recording site. One side barrel of the five-barrel micropipette is loaded with 4 M NaCI for automatic current balancing and the others with three of the following solutions: L-epinephrine bitartrate (0. l M, pH 4.0), L-norepinephrine bitartrate (0.1 M, pH 4.0), Substance P (2.75 mM), physalaemin (2.6 mM), substance P 4-11 octapeptide (3.1 mM), eledoisin-related peptide (20 mM), neurotensin, bradykinin triacetate (15 mM), met-enkephalin (6.5 mM), TRH (48 mM). Spontaneously active cells are recorded in the locus coeruleus or in the nearby mesencephalic nucleus of the fifth nerve whose cells are easily identified by their increased activity upon manipulation of the jaw[2].
