Guangxitoxin 1E 产品活性：Guangxitoxin 1E 是 KV2.1 和 KV2.2 通道的有效选择性阻断剂。Guangxitoxin 1E 抑制 KV2， 其 IC50 值为 1-3 nM，KV2 通道是各种神经元中延迟整流器钾电流的基础。 产品来源： https://www.medchemexpress.cn/guangxitoxin-1e.html 研究领域：Membrane Transporter/Ion Channel 作用靶点：Potassium Channel In Vitro: Guangxitoxin 1E inhibits KV2 with an IC50 of 1-3 nM but has no significant effect on KV1.2, KV1.3, KV1.5, KV3.2 and BK potassium channels, nor on calcium and sodium channels CaV1.2, CaV2.2, NaV1.5, NaV1.7, NaV1.8, whereas the IC50 for KV4.3 channels is 24-54 nM. In mouse β-cells, Guangxitoxin 1E inhibits 90% of IDR and, as for KV2.1, shifts the voltage dependence of channel activation to more depolarized potentials, a characteristic of gating-modifier peptides. Guangxitoxin 1E broadens theβ-cell action potential, enhances glucose-stimulated intracellular calcium oscillations, and enhances insulin secretion from mouse pancreatic islets in a glucose-dependent manner. 相关产品：Nigericin sodium salt | Yoda 1 | BAPTA-AM | Minocycline hydrochloride | Branaplam | Rosuvastatin Calcium | SCH-23390 hydrochloride | Glibenclamide | Quinidine (15% dihydroquinidine) | Carbamazepine | Tetrandrine | E-4031 | DCPIB | Minoxidil | Amiodarone hydrochloride | 20(S)-Ginsenoside Rg3 | Guanosine 5'-diphosphate disodium salt | Tannic acid | Quinine | TRAM-34 | SKF-96365 hydrochloride | (±)-Naringenin | Astemizole | PAP-1 | Terfenadine | Flufenamic acid | Ifenprodil tartrate | 4-Aminopyridine | Mefloquine hydrochloride | GW9508 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
