体外研究
(In Vitro)

(Leu31,Pro34)-Peptide YY 在大鼠额顶叶皮质膜制剂 (Y1富集组织) 和兔大隐静脉 (Y1体外生物测定) 中表现出高亲和力 (nM)，但在 Y2富集制剂 (大鼠海马) 中仅表现出低亲和力[1]。

体内研究
(In Vivo)

(Leu31,Pro34)-Peptide YY (0.1-1 nmol/day; ICV; 14 days) 对大鼠有抗焦虑和抗抑郁作用[2]。

Animal Model:Male Sprague Dawley rats weighing 150-170 g, OBX/Sham model[2]
Dosage:0.1, 0.3 and 1 nmol/day
Administration:ICV, for 14 days
Result:Significantly decreased hyperlocomotion and immobility time in OBX animals. Reversed the deficit in social contacts in OBX animals. Reduced grooming behavior in sham animals.

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:

 ContentsAssign value
Acidic amino acidAsp (D), Glu (E), and the C-terminal -COOH.-1
Basic amino acidArg (R), Lys (K), His (H), and the N-terminal -NH2+1
Neutral amino acidGly (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 peptideDetails
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.
