生物活性

Gap 26 is a connexin mimetic peptide, composed of residue numbers 63-75 of the first extracellular loop of connexin 43 (gap junction blocker), containing the SHVR amino acid motif.

体外研究(In Vitro)

Gap 26 (0.25 mg/mL, 30 min) reduces the wave size in the three cell lines (RBE4, SV-ARBEC and ECV304). Gap 26 (0.25 mg/mL, 30 min) completely abolishes the InsP3-triggered ATP response and reduced the ATP release to below the control level, indicating that the basal ATP release is also affected.
Gap 26 does indeed significantly inhibit our InsP3-triggered intercellular calcium waves, but it did not have any effect on dye coupling through junctional channels as evidenced by the FRAP experiments, despite the fact that connexin 43 was present in the cell lines used.
Gap 26 (100-300 μM) dose-dependently reduces the rhythmic responses of rabbit superior mesenteric arteries, with IC50 of 28.4 ± 3.4 μM.

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

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
