生物活性

Amylin, amide, human TFA, a 37-amino acid polypeptide, is a pancreatic hormone cosecreted with insulin that exerts unique roles in metabolism and glucose homeostasis. Amylin, amide, human TFA inhibits glucagon secretion, delays gastric emptying, and acts as a satiety agent[1].

体外研究
(In Vitro)

MCF-7 cells endogenously express human amylin receptor CTR1 and CTR2. Stimulation of the receptor with Amylin, amide, human results in the production of cAMP. Amylin, amide, human (0.001 nM-1000 μM) results in an EC50 of 35.2±7.5 nM[1].

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

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.
