Rhodamine 800

CAS No. : 137993-41-0

MCE 国际站：Rhodamine 800

产品活性：罗丹明类染料是一种膜渗透性的阳离子荧光探针，可对线粒体膜电位进行特异性识别，从而附着在线粒体中，并产生明亮荧光，在一定浓度下，罗丹明类染料对细胞具有低毒性，因此普遍用于检测动物细胞、植物细胞以及微生物中的线粒体。

研究领域：Others

作用靶点：Fluorescent Dye

In Vitro: 1.Preparation of Rhodamine 800 working solution
1.1Preparation of the stock solution
Dissolve 1 mg Rhodamine 800 in 525 μL DMSO to obtain 5 mM of stock solution.
1.2Preparation of Rhodamine 800 working solution
Dilute the stock solution in serum-free cell culture medium or PBS to obtain 1-20 μM of working solution.
Note: Please adjust the concentration of Rhodamine 800 working solution according to the actual situation.
2.Cell staining
2.1 Suspension cells (6-well plate)
a.Centrifuge at 1000 g at 4℃ 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 5-30 minutes.
c.Centrifuge at 400 g at 4℃ 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 flow cytometry.
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 30-60 minutes.
d.Wash twice with medium, 5 minutes each time. Observation by fluorescence microscopy or flow cytometry.
Note: If detection by flow cytometry, cells need to be resuspended before staining.
