生物活性
Amylin (8-37), human is a fragment of human Amylin. Amylin (8-37), human has direct vasodilator effects in the isolated mesenteric resistance artery of the rat. Human Amylin is a small hormone secreted by pancreatic β-cells that forms aggregates under insulin deficiency metabolic conditions, and it constitutes a pathological hallmark of type II diabetes mellitus[1].
Room temperature in continental US; may vary elsewhere.

Amylin (IAPP), feline, a 37-amino acid polypeptide. Amylin (IAPP) is one of the major secretory products of β-cells of the pancreatic islets. Amylin (IAPP) is a regulatory peptide, which inhibits insulin and glucagon secretion[1].

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.
