产品名称

Neuromedin U (rat)
Rat neuromedin U-23

产品介绍

Neuromedin U, rat 是一种含 23 个氨基酸的脑肠肽,，通过其中枢神经系统中的同源受体 NMUR2 调节几种重要的生理功能，包括能量平衡，应激反应和伤害感受。

生物活性

Neuromedin U, rat is a 23-amino acid brain-gut peptide. Neuromedin U (NMU), through its cognate receptor NMUR2 in the central nervous system, regulates several important physiological functions, including energy balance, stress response, and nociception.

IC₅₀& Target

NMUR2^[1]

体外研究
(In Vitro)

To establish an electrochemiluminescent (ECL) binding assay for NMUR2 receptor, the peptide Neuromedin U (NMU-23) is labeled at the N terminus with Ru(bpy)²⁺₃and allowed to bind to the human NMUR2 receptor in the cell membranes immobilized on the electrode on the bottom of each assay plate. Upon application of an electric current, the receptor-bound Ru(bpy)²⁺₃-ligand undergoes an oxidation-reduction cycle in the presence of a coreactant tripropylamine and emits light. Signal is only generated when the Ru(bpy)²⁺₃label is in proximity to the electrode, thus discriminating the bound label from the unbound and enabling a no wash, homogenous assay format. The ECL-based NMUR2 binding assay is used to screen our corporate compound collection. Approximately 670,000 compounds with diverse structures are tested at 10 μM for their ability to displace the binding of 0.5 nM Ru(bpy)²⁺₃-NMU-23 to human NMUR2 receptors. From competition binding experiments, the K_ivalues for NMU-23 is determined to be 4.7 nM^[1].

Solvent & Solubility

In Vitro:

H₂O

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.
