生物活性

Apraglutide TFA (FE 203799 TFA), a synthetic 33-amino-acid peptide and a long-acting GLP-2 analogue, enhances adaptation and linear intestinal growth in a neonatal piglet model of short bowel syndrome with total resection of the ileum[1].

体内研究
(In Vivo)

Apraglutide (FE 203799; 5 mg/kg/dose, subcutaneously, twice on days 0 and 4 postsurgery) treated piglets are healthy, have significant lower fecal fat and energy losses and exhibite intestinal lengthening, greater small-intestinal weight, longer villus height, and greater crypt depth on day 7[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: NewbornDuroc piglets, 2-5 days old and weighing between 2-2.6 kg[1].
Dosage: 5 mg/kg/dose.
Administration: Subcutaneously, twice on days 0 and 4 postsurgery.
Result: On day 7, treated piglets were healthy, had significant lower fecal fat and energy losses and exhibited intestinal lengthening, greater small-intestinal weight, longer villus height, and greater crypt depth.

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.
