产品介绍

[D-Trp34]-Neuropeptide Y TFA 是有效的，选择性神经肽 Y (NPY)Y5受体激动剂。[D-Trp34]-Neuropeptide Y TFA 在 NPY Y₁，Y₂，Y₄和 y₆受体上的效力明显较低。[D-Trp34]-Neuropeptide Y TFA 明显增加大鼠的食物摄入量。

生物活性

[D-Trp34]-Neuropeptide Y TFA is a potent and selectiveneuropeptide Y (NPY) Y₅receptoragonist. [D-Trp34]-Neuropeptide Y TFA is a significantly less potent agonist at the NPY Y₁, Y₂, Y₄, and y₆receptors. [D-Trp34]-Neuropeptide Y TFA markedly increases food intake in rats^[1]^[2].

NPY Y₅receptor

体外研究
(In Vitro)

[D-Trp34]-Neuropeptide Y TFA has pK_ivalues of 6.49, 5.43, 7.08, 7.53, 6.55, 5.95, 6.85, 7.41 for hY₁, hY₂, hY₄, hY₅, rY₁, rY₂, rY₄, rY₅in CHO cells. [D-Trp34]-Neuropeptide Y TFA has pEC₅₀values of 6.44,<6, 6.28，7.82 for rY₁, rY₂in CHO cells and rY₄, rY₅in HEK-293 cells^[1].

体内研究
(In Vivo)

[D-Trp34]-Neuropeptide Y TFA (0, 8 and 16 μg/rat; I.C.V) stimulats food intake to the same extent in both lean and obese rats 1 h after injection at a dose of 16 μg in male Zucker rats^[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.
