General description

Tetramethylrhodamine ethyl ester perchlorate (TMRE), also known as TMRE perchlorate, is a potential mitochondrial dye. TMRE staining process is reversible, and it doesn’t affect cell proliferation and viability.

The sorted cells containing TMRE perchlorate don’t interfere with the subsequent functional assays and hence are a preferred choice for the enrichment of functionally active, unbiased cell populations.

Application

Tetramethylrhodamine ethyl ester perchlorate (TMRE) is used to study the effects of high glucose in inducing mitochondrial morphology and metabolic changes.

TMRE perchlorate is also used to study Fullerene C 60 penetration into Leukemic Cells and the subsequent photoinduced Cytotoxic Effects.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Mitochondrial ribosomal proteins are important for mitochondrial-encoded protein synthesis and mitochondrial function. In addition to their roles in mitoribosome assembly, several mitochondrial ribosome proteins are also implicated in cellular processes like cell cycle regulation, apoptosis, and mitochondrial homeostasis regulation.
