MQAE 产品活性：MQAE 是一种紫外激发的新型氯离子荧光探针，激发/发射波长为 350/460 nm，用于检测氯离子活性。MQAE 以溴离子做配体，当细胞内氯离子浓度升高时，其荧光强度会不断的降低，当氯离子摩尔浓度低于 50 nM 时，其荧光强度基本不受 pH 影响。MQAE 的细胞渗透性很高，可适用于共聚焦显微镜与流式细胞仪等荧光检测。 产品来源： https://www.medchemexpress.cn/MQAE.html 研究领域：Others 作用靶点：Fluorescent Dye In Vitro: General Protocol 1 Preparation of MQAE working solution 1.1 Preparation of the stock solution Dissolve 1 mg MQAE in 0.3066 mL DMSO to obtain 10 mM of MQAE. Note: It is recommended to store the stock solution at -20°C -80°C away from light and avoid repetitive freeze-thaw cycles. 1.2 Preparation of MQAE working solution Dilute the stock solution in Krebs-hepes buffer (20 mM HEPES, 128 mM NaCl, 2.5 mM KCl, 2.7 mM CaCl2, 1 mM MgCl2, 16 mM glucose, pH 7.4) to obtain 5-10 mM of MQAE working solution. Note: Please adjust the concentration of MQAE working solution according to the actual situation. 2 Cell staining 2.1 For suspension cells: Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time. For adherent cells: Discard the cell culture medium, and add trypsin to dissociate cells to make a single-cell suspension. Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time. 2.2 Add 1 mL of MQAE working solution, and then incubate at room temperature for 30 minutes. 2.3 Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant. 2.4 Wash twice with PBS, 5 minutes each time. 2.5 Resuspend cells with serum-free cell culture medium or PBS. 3 Storage -20°C, 1 year. Protect from light. 4 Precautions 4.1 It is recommended to store the stock solution at -20°C or -80°Caway from light and avoid repetitive freeze-thaw cycles. 4.2 Please adjust the concentration of MQAE working solution according to the actual situation. 4.3 This product is for R&D use only, not for drug, household, or other uses. 4.4 For your safety and health, please wear a lab coat and disposable gloves to operate. 相关产品：MitoSOX Red | BODIPY 493/503 | D-Luciferin potassium | Nile Red | FITC | JC-1 | Propidium Iodide | DiR | FITC-Dextran (MW 4000) | Dihydroethidium | CFDA-SE | 2-NBDG | Calcein-AM | DiI | Thiazolyl Blue | Cy5.5 | TMRE | Fluo-4 AM | CY5 | Indocyanine green | PKH 26 | DiD perchlorate | Acridine Orange hydrochloride | BODIPY 581/591 C11 | FM4-64 | DiO | CY5-SE 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。
