The MitoPT™ TMRM kit uses a quick and easy staining method to clearly differentiate between non-apoptotic and apoptotic cells through mitochondrial functionality.

Product Details

Reagents in the Kit
MitoPT™ TMRM Reagent - lyophilized - to make up 1mM stock
10X Assay Buffer, 125mL
600uL vial 50mM Carbonylcyanide m - chlorophenylhydrazone (CCCP) concentrate in DMSO.
Test Principle
An early indication of apoptosis involves a collapse in the electrochemical gradient across the mitochondrial membrane. Loss of mitochondrial membrane potential can be detected by a unique fluorescent cationic dye known as TMRM (tetramethylrhodamine methyl ester), that has been incorporated into the MitoPT™ TMRM kit.

The MitoPT™ TMRM reagent easily penetrates cells and enters the mitochondria. It aggregates in the mitochondria of non-apoptotic cells and fluoresces bright orange/red, whilst in apoptotic cells it diffuses throughout the cell. Once dispersed, the reagent assumes a monomeric form and exhibits a reduced orange/red fluorescence level. This allows an easy distinction between apoptotic and non-apoptotic fluorescent cells which can be read with a flow cytometer, fluorescence microscope or a fluorescence plate reader using black microtitre plates.

Storage Information

Store the unopened kit (and each unopened component) at -20°C until the expiration date. Protect the MitoPT™ TMRM reagent from light at all times.

Once reconstituted, the 1mM MitoPT™ TMRM stock should be stored at -20°C protected from light.
Guaranteed until date of expiry. Please see product label.
