Image-iT™ TMRM 试剂（线粒体膜电位指示剂）

正常线粒体膜维持着细胞器内外之间的电势差异，称为膜电位。四甲基罗丹明甲基酯（Tetramethylrhodamine, methyl ester，以下简称 TMRM）是一种能透过细胞的染料，可在具有完整膜电位的活性线粒体中累积。如果细胞线粒体正常且发挥功能，会发出荧光信号。一旦线粒体膜电位丢失，TMRM 不再累积，荧光信号变弱或消失了解更多信息

常见问题解答 (FAQ)

For a final staining solution, we can add TMRM directly into cell growth medium. Can this media contain serum?

Yes, you may add TMRM to media with serum. Serum components may bind dye non-specifically so you may need a higher final working concentration for staining samples in media containing serum relative to staining the same cells in a non-serum media or buffer.

How is TMRM different from the MitoTracker dyes?

TMRM is a dynamic mitochondrial stain. There is no covalent attachment of TMRM to the mitochondria and because of this, it can move in and out of the mitochondria dependent upon changes in the membrane potential. The MitoTracker dyes on the other hand possess a reactive chloromethyl group that allows for their covalent attachment to mitochondria. As a result, once they accumulate within mitochondria that have a normal membrane potential, they are retained.

What is included in the Image-iT TMRM Reagent (Cat No. I34361)?

The Image-iT TMRM Reagent is a ready-to-use 1,000X concentrated stock solution of the TMRM dye. It contains 5 vials of 100 µM of TMRM in neat DMSO, with 100 µL volume in each vial. TMRM powder (Cat No. T668) is not included in this kit.

Abstract
miR-450a Acts as a Tumor Suppressor in Ovarian Cancer by Regulating Energy Metabolism.
Authors:Muys BR, Sousa JF, Plaça JR, de Araújo LF, Sarshad AA, Anastasakis DG, Wang X, Li XL, de Molfetta GA, Ramão A, Lal A, Vidal DO, Hafner M, Silva WA
Journal:Cancer Res
PubMed ID:31101765
'Dysregulation of miRNA expression is associated with multiple diseases, including cancers, in which small RNAs can have either oncogenic or tumor suppressive functions. Here we investigated the potential tumor suppressive function of miR-450a, one of the most significantly downregulated miRNAs in ovarian cancer. RNA-seq analysis of the ovarian cancer cell ... More
Ursodeoxycholic acid protects against cisplatin-induced acute kidney injury and mitochondrial dysfunction through acting on ALDH1L2.

PubMed ID:32004633
'Mitochondrial dysfunction plays an important role in acute kidney injury (AKI). Thus, the agents improving the mitochondrial function could be beneficial for treating AKI. Ursodeoxycholic acid (UDCA) has been demonstrated to prevent mitochondrial dysfunction under pathology, however, its role in AKI and the underlying mechanism remain unknown. This study aimed ... More
Targeting mitochondria-associated membranes as a potential therapy against endothelial injury induced by hypoxia.
Authors:Yang YD, Li MM, Xu G, Zhang EL, Chen J, Sun B, Chen DW, Gao YQ
Journal:J Cell Biochem
PubMed ID:31241212
Mitochondrial dysfunction plays a principal role in hypoxia-induced endothelial injury, which is involved in hypoxic pulmonary hypertension and ischemic cardiovascular diseases. Recent studies have identified mitochondria-associated membranes (MAMs) that modulate mitochondrial function under a variety of pathophysiological conditions such as high-fat diet-mediated insulin resistance, hypoxia reoxygenation-induced myocardial death, and hypoxia-evoked vascular smooth ... More
Barrier-to-Autointegration Factor 1 Protects against a Basal cGAS-STING Response.

Journal:mBio
PubMed ID:32156810
Although the pathogen recognition receptor pathways that activate cell-intrinsic antiviral responses are well delineated, less is known about how the host regulates this response to prevent sustained signaling and possible immune-mediated damage. Using a genome-wide CRISPR-Cas9 screening approach to identify host factors that modulate interferon-stimulated gene (ISG) expression, we identified ... More
Mitochondrial Pyruvate Carrier 1 Promotes Peripheral T Cell Homeostasis through Metabolic Regulation of Thymic Development.

Journal:Cell Rep
PubMed ID:32130894
Metabolic pathways regulate T cell development and function, but many remain understudied. Recently, the mitochondrial pyruvate carrier (MPC) was identified as the transporter that mediates pyruvate entry into mitochondria, promoting pyruvate oxidation. Here we find that deleting Mpc1, an obligate MPC subunit, in the hematopoietic system results in a specific reduction ... More
