生物活性

Gap19, a peptide derived from nine amino acids of the Cx43 cytoplasmic loop (CL), is a potent and selective connexin 43 (Cx43) hemichannel blocker. Gap19 inhibits hemichannels caused by preventing intramolecular interactions of the C-terminus (CT) with the CL. Gap19 is not blocking GJ channels or Cx40/pannexin-1 hemichannels. Gap19 has protective effects against myocardial[1][2].

IC50 & Target

Cx43 Hemichannel[1]

体外研究
(In Vitro)

Gap19 (250 μM; for 30 min ) decreases mitochondrial potassium uptake[1].
Gap19 (400 μM) inhibits unitary hemichannel currents in HeLa-Cx43 cells[2].
Gap19 (100 μM) inhibits hemichannel unitary currents in ventricular cardiomyocytes[2].
Gap19 (250 μM, 30 min) protects against myocardial ischemia/reperfusion injury in vitro and in vivo[2].

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

体内研究
(In Vivo)

Gap19 (iv; 25 mg/kg; 10 min before ligation) significantly reduces the infarct size by approximately one-fifth[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
