| 生物活性 |
TAT-Gap19, a Cx mimetic peptide, is a specific connexin43 hemichannel (Cx43 HC) inhibitor. TAT-Gap19 does not inhibits the corresponding Cx43 GJCs. TAT-Gap19 traverses the blood-brain barrier and alleviate liver fibrosis in mice[1][2][3].

体内研究
(In Vivo) |
A single injection of TAT-Gap19 (i.v. via the tail vein; 55 mg/kg) produces significant immune signal in the brain 24 h later in 4 months old C57Bl6 male mice[1].
TAT-Gap19 (1 mg/kg/day; an osmotic pump implanted in the peritoneal cavity; Two weeks) shows significantly decreased collagen deposition, as well as lowed amounts of α-SMA-positive cells area in mice subjected to treatment with 100-200 mg thioacetamide (TAA)/kg body weight for eight weeks[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. |
