Description

GLP-1(32-36)amide TFA, a pentapeptide, derived from the C terminus of the glucoregulatory hormone GLP-1. GLP-1(32-36)amide TFA could inhibit weight gain and modulate whole body glucose metabolism in diabetic mice[1][2].

In Vitro

GLP-1(32-36)amide (0.1-10 μM; 24 h) retains cell viability and decreases apoptosis against Streptozotocin (STZ; 1 μM) in INS‐1 cells[2].

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

Cell Viability Assay[2]

Cell Line: INS‐1 cells
Concentration: 0.1, 1, 10 μM
Incubation Time: 24 hours
Result: Decreased cell viability only approximately 30% in 0.1 μM and approximately 20% in ≥1 μM while approximately 45% in saline-treated controls.
In Vivo

GLP-1(32-36)amide (1 μmol/kg; i.p. once daily for 21 d) protects islet from damage, inhibits weight gain, and relieves symptoms of polydipsia in diabetic mice[2].
GLP-1(32-36)amide (1 μmol/kg; a single i.p.) slightly reduces the mean glucose lever at 30 min after the challenge of glucose in normal mice[2].
GLP-1(32-36)amide (50-70 nmol/kg/d; infusion for 12-16 weeks) prevents the development of diet-induced obesity and hepatic steatosis in high fat-fed mice[3].

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

Animal Model: Male KM mice (6-8 weeks; 18-22 g) injected with STZ[2]
Dosage: 1 μmol/kg
Administration: 1 μmol/kg
Result: Significantly lowered the cumulative values of food and water intake.
Lowered fasting glucose.
Reduced the level of Hemoglobin A1c (HbA1c).
Improved glucose tolerance.
Suppressed body weight gain.

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.
