生物活性

Pramlintide TFA is a polypeptide analogue of human amylin. Pramlintide TFA, an antidiabetic agent, is antineoplastic in colorectal cancer[1].

体外研究
(In Vitro)

Pramlintide inhibits the growth of HCT-116 and HT-29 in a dose-dependent manner, with higher efficacy against the latter (IC50s of 48.67 and 9.10 μg/mL, respectively)[1].
The addition of 5, 10, and 20 μg/mL of Pramlintide to HCT-116 and HT-29 with 5-fluorouracil, Oxaliplatin, or Irinotecan induces the antiproliferative effect synergistically[1].

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.
