| 生物活性 |
Ac2-12 TFA, an annexin/lipocortin 1 (LC1)-mimetic peptide, inhibit neutrophil extravasation. Ac2-12 TFA has antimigratory action and inhibits recruitment of neutrophils in experimental inflammation models[1][2].

体内研究
(In Vivo) |
Ac2-12 TFA (i.v.; 6.7 mg/kg, ≈70 nmol per mouse), was found to mimic the actions of lipocortin 1 (LC1) and Ac2-26 in male Swiss Albino mice (10-15 g)[1].
Ac2-12 TFA (100 μg) significantly reduces polymorphonuclear leukocyte (PMN) influx in wild-type C57BL/6 mice and is no longer active in FPR KO mice[2].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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. |
