产品使用指南

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。

    Mitochondrial membrane potential detected by TMRE. TMRM staining reveals a decreased signal in the Immp2l knockdown granulosa cells compared to control cells, suggesting mitochondrial membrane potential depolarization. Melatonin treatment prevented the membrane depolarization in Immp2l knockdown granulosa cells.

    生物活性

    Rhodamine dyes are membrane-permeable cationic fluorescent probes that specifically recognize mitochondrial membrane potentials, thereby attaching to mitochondria and producing bright fluorescence, and at certain concentrations, rhodamine dyes have low toxicity to cells, so they are commonly used to detect mitochondria in animal cells, plant cells, and microorganisms[1].

    Cell Assay
    [1]

    Cultures are exposed to Millipore-filtered solutions (0.22 µm) containing TMRM and/or drugs for 1 hr at 37°C (except the experiment involving different durations of exposure to TMRM). After treatment, solutions are removed and growth media reapplied under sterile conditions, and cultures are post-incubated for 18 hours at 37°C (except for the experiment involving analysis at different time points after exposure). Cells are then stained with 2 mg/mL bisbenzimide for 20 min at room temperature. Coverslips are subsequently washed in saline and imaged using 2P microscopy. Apoptotic cells are identified as brightly fluorescent nuclei under UV excitation indicating DNA fragmentation. Cell survivability is calculated as the percentage of live, unstained cells (±SD) in five microscopic fields per treatment[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
