Field of application
Gap 27 is a synthetic connexin-mimetic peptide and acts as a gap junction inhibitor. Gap 27 is highly effective in interrupting co-operative cell-cell interactions, such as the synchronous beating of embryonic cardiomyocytes.

Description: Gap 27, connexin43 mimetic peptide, is a gap junction inhibitor.
In Vivo: Gap 27 (300 μM) inhibits relaxation by 40% in thoracic aorta and the superior mesenteric artery. Gap 27 also attenuates the endothelium-dependent component of the relaxation induced by ATP in thoracic aorta. [3].
In Vitro: Gap 27 causes a remarked decrease in the number of both TRAP-positive mononuclear and multinucleated rat osteoclasts cultured on bovine bone slices. The activity of the remaining osteoclasts is found to be diminished by measuring the percentage of osteoclasts with actin rings of all TRAP-positive cells. In addition, the resorbed area in the treated cultures is greatly diminished[1]. Incubation of the carotid artery with the gap junction inhibitor Gap 27 (500 μM) essentially abolishes the hyperpolarization to acetylcholine but it is without effect on that to levcromakalim. In the guinea-pig isolated internal carotid artery, Gap 27 inhibits acetylcholine-induced, endothelium-dependent hyperpolarizations[2].
Cell Assay: Bone cell cultures are cultured for 48 hours with three different treatments (control, heptanol and Gap 27). After the culture period, bone slices are fixed. The cells are stained for tartrate-resistant acid phosphatase (TRAP). To visualise the nuclei, the cells are incubated with the DNA-binding fluorochrome Hoechst 33258 (1 mg/mL stock diluted 1:800 in PBS) for 10 minutes at room temperature. The numbers of mononuclear and multinucleated TRAP-positive cells on each bone slice are counted[1].

DC46690 Gap 27 Gap 27 is a synthetic connexin-mimetic peptide and acts as a gap junction inhibitor. Gap 27 is highly effective in interrupting co-operative cell-cell interactions, such as the synchronous beating of embryonic cardiomyocytes.
DC29103 Gap19 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.
