Calcein-AM 产品活性：Calcein AM，中文名为该黄绿素乙酰氧基甲指，具细胞膜渗透性，可轻易进入到细胞内，Calcein AM 身并无荧光，进入细胞后被细胞中内源性酯酶水解生成具有强负电荷的不能通透细胞膜的极性分子钙黄绿素 (Calcein)，从而被滞留在细胞内。而 Calcein 可发出强绿色荧光，因此常与 Propidium Iodide 用于细胞活力/毒力检测，激发/发射波长：494/515 nm。 产品来源： https://www.medchemexpress.cn/Calcein-AM.html 研究领域：Others 作用靶点：Fluorescent Dye In Vitro: General Protocol 1.Preparation of Calcein AM working solution Preparation of 5 mM stock solution with DMSO. Dilute the stock solution in serum-free cell culture medium or PBS to obtain 1-10 μM of working solution. Note: Please adjust the concentration of Calcein AM working solution according to the actual situation. 2.Cell staining 2.1 Suspension cells（6-well plate） a.Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.The cell density is 1×106/mL. b.Add 1 mL of working solution, and then incubate at room temperature for 30-45 minutes. c.Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant. d.Wash twice with PBS, 5 minutes each time. e.Resuspend cells with serum-free cell culture medium or PBS. Observation by fluorescence microscopy or fluorescence microplate readers. 2.2 Adherent cells a.Culture adherent cells on sterile coverslips. b.Remove the coverslip from the medium and aspirate excess medium. c.Add 100 μL of working solution, gently shake it to completely cover the cells,and then incubate at room temperature for 30-45 minutes. d.Wash twice with medium, 5 minutes each time. Observation by fluorescence microscopy or fluorescence microplate readers. Storage -20°C Protect from light Precautions 1.Please adjust the concentration of Calcein AM working solution according to the actual situation. 2.This product is for R&D use only, not for drug, household, or other uses. 3.For your safety and health, please wear a lab coat and disposable gloves to operate. In Vivo: Calcein-AM is found to be suitable for in vivo studies, because it has no deleterious effects on cell function and is, indeed, a marker of cell viability. 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 | 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 | TMRM Perchlorate 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。
