Product DescriptionCalcein-AM readily passes through the cell membrane of viable cells because of its enhanced hydrophobicity compared to Calcein. After Calcein-AM permeates into the cytoplasm, it is hydrolyzed by esterases to Calcein, which remains inside the cell (Fig. 1). Among other reagents, including BCECF-AM and Carboxy-fluorescein diacetate, Calcein-AM is the most suitable fluorescent probe for staining viable cells because of its low cytotoxicity. Calcein does not inhibit any cellular functions such as proliferation or chemotaxis of lymophocyte. In addition, viability assays using Calcein are reliable and correlate well with the standard 51Cr-release assay. The excitation and emission wavelengths of calcein are 490 nm and 515 nm, respectively

Fig. 1 Cell staining mechanism

Staining Procedure1.Prepare 1 mM Calcein-AM solution with DMSO and dilute to prepare 1-50 μM Calcein-AM solution with PBS.a)2.Add Calcein-AM solution with 1/10 of the volume of cell culture medium to the cell culture.b)3.Incubate the cell at 37ºC for 15-30 min.4.Wash cells twice with PBS or an appropriate buffer.5.Observe the cells under a fluorescence microscope with 490 nm excitation and 515 nm emission filters.

a) If the Calcein-AM has difficulty loading into cells, use a detergent such as Pluronic F127.b) Or you may replace the culture medium with 1/10 concentration of Calcein-AM buffer solution.

Dojindo细胞分析细胞活力和细胞毒性测定用于药物筛选和化学物质的细胞毒性测试。Dojindo开发了高度水溶性的四唑盐,称为WST。WST-8是高度稳定的WST,用于Cell Counting Kit-8(CCK-8)。由于WST-8甲maz是水溶性的,因此不会形成晶体。因此,不需要诸如MTT测定的增溶过程。此外,CCK-8的检测灵敏度高于其他四唑盐,例如MTT,XTT,MTS或WST-1。WST检测机制 ß-半乳糖苷酶检测试剂细胞增殖/细胞毒性转染细胞染色细胞内荧光探针细菌染色微生物活力测定干细胞分化SPiDER-ßGal线粒体检测细胞代谢应用产品展示细胞生长检测,药物筛选,比色/荧光检测细胞计数试剂盒-8细胞计数试剂盒8 + 96孔有机硅定向剂细胞计数试剂盒-F细胞毒性LDH检测试剂盒-WST 96孔有机硅定向剂MTT了解检测机制的差异:点击这里细胞周期分析细胞周期测定溶液深红色细胞周期测定溶液蓝色
