Diphenyl Blue 产品活性：Diphenyl Blue (Trypan Blue) 是一种细胞活性染料，最常用的死细胞鉴定染料，常用于检测细胞膜的完整性和细胞的存活率。Diphenyl Blue 染色是组织和细胞培养中方法之一。细胞丧失活性或细胞膜不完整时，Diphenyl Blue 可将其染成蓝色，正常的活细胞细胞膜结构完整，能够排斥 Diphenyl Blue，细胞不会被染成蓝色。但巨噬细胞能够吞噬 Diphenyl Blue，所以可用于巨噬细胞的活体染色剂。 产品来源： https://www.medchemexpress.cn/Diphenyl_Blue.html 研究领域：Others 作用靶点：Fluorescent Dye In Vitro: Preparation of Trypan Blue working solution 1.1 Preparation of the stock solution Dissolve 10 mg of Trypan Blue in 100 mL 0.85% Nacl to obtain 0.4% Trypan Blue. Note: It is recommended to store the stock solution at -20℃ -80℃ away from light and avoid repetitive freeze-thaw cycles. 1.2 Preparation of Trypan Blue working solution Dilute the stock solution in 0.85% Nacl to obtain 0.04% of Trypan Blue working solution. Note: Please adjust the concentration of Trypan Blue working solution according to the actual situation. Cell staining 2.1 For suspension cells, centrifuge at 1000 g at 4℃ 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℃ for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time. 2.2 Add 1 mL of rypan Blue working solution, and then incubate at room temperature for 5 minutes. 2.3 Centrifuge at 400 g at 4℃ 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, and then detect by fluorescence microscope. 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。
