商品信息

JC-1 (CBIC2) 是荧光亲脂性羰花青染料,用于测量线粒体膜电位。线粒体膜电位较高时, JC-1 在基质中汇聚形成聚合物 (J-aggregates),可以产生红色荧光 (Ex/Em=585/590 nm);线粒体膜电位较低时,JC-1 不能聚集在线粒体基质中,以单体形式存在产生绿色荧光 (Ex/Em=510/527 nm)


生物活性

JC-1 (CBIC2) is a fluorescent lipophilic carbocyanine dye used to measure mitochondrial membrane potential. JC-1 forms complexes known as J-aggregates at high ΔΨm. Aggregates of JC-1 emit an orange-red fluorescence (Ex/Em=585/590 nm). While in cells with low ΔΨm, JC-1 remains in the monomeric form. JC-1 monomers emit a green fluorescence (Ex/Em=510/527 nm).

体外研究
(In Vitro)

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Labeling of Cells:
1. Culture cells in 6-, 12- , 24-, or 96-well plates at a density of 5× 10
5 cells/mL. Incubate the cells according to your normal protocol.
2. Ensure that the JC-1 and DMSO has equilibrated to room temperature, and then prepare a 200 μM stock solution by dissolving the contents of one vial in DMSO provided.
3. For the control tube, allow the vial of CCCP has come to room temperature, add 1 μL of CCCP (50 mM). Incubate cells at 37°C for 5 minutes.
4. Add 10 μL JC-1 (200 μM) per well to make the final concentration at 2 μM. Incubate cells at 37°C, 5% CO
2, for 15-20 minutes. If additional labeling followed, for example with an annexin V, begin with step 2.a. If not, proceed with step 1.e.
5. After incubation, centrifuge cells for 3-4 minutes at 400× g at 4°C, carefully aspirate the supernant.
6. Wash cells twice with PBS (1×): add 2 mL PBS (1×) to suspend cells and vortex to mix thoroughly. Centrifuge cells for 3-4 minutes at 400× g at 4°C, carefully aspirate the supernant.
7. Add 500 μL PBS (1×) to suspend cells. Analyze sample on a flow cytometer, fluorescence microscopy, or fluorescence microplate reader.
