MitoTracker Green (MTG) is a mitochondrial-selective fluorescent label commonly used in confocal microscopy and flow cytometry. It is expected that this dye selectively accumulates in the mitochondrial matrix where it covalently binds to mitochondrial proteins by reacting with free thiol groups of cysteine residues.
How does MitoTracker deep red work?
MitoTracker® Deep Red binds thiol‐reactive chloromethyl groups in the mitochondrial membrane and is retained after cell fixation, whereas MitoTracker® Green binds free thiol groups of cysteine residues belonging to mitochondrial proteins and can only be used with non‐fixed cells.
How do you use a MitoTracker?
Popular Answers (1)
- Remove medium from the cells and add prewarmed medium with MitoTracker (most commonly used concentration is in the range of 300-400 nmol).
- Incubate for 45 to 60 minutes.
- Exchange the medium with regular one and incubate for 5 min, repeat 2 more times.
What is RFP in cell biology?
Red fluorescent protein (RFP) is a versatile biological marker for monitoring physiological processes, visualizing protein localization, and detecting transgenic expression in vivo. RFP can be excited by the 488 nm or 532 nm laser line and is optimally detected at 588 nm.
What does MitoTracker measure?
MitoTracker green (MTG) and nonylacridine orange (NAO) are fluorescent probes which have been commonly used to assess mitochondrial mass. This is based on the assumption that both MTG and NAO accumulate in mitochondria regardless of the mitochondrial transmembrane potential (ΔΨm).
Can a MitoTracker be fixed?
For MitoTracker® Red CMXRos, we have found that fixing with 3.7% formaldehyde in complete growth medium at 37°C for 15 minutes works well for endothelial cells.
What are MitoTracker?
MitoTracker is a commercially available fluorescent dye (Invitrogen/Molecular Probes) that, like the aforementioned dyes, labels mitochondria within live cells utilizing the mitochondrial membrane potential. In addition, it can be used in experiments in which multiple labeling diminishes mitochondrial function.
What is GFP and RFP?
Green Fluorescent Protein (GFP) and Red Fluorescent Protein (RFP) are ~29 kDa fluorescent proteins used as versatile markers for visualization of protein localization, monitoring physiological processes, and for detecting transgenic or transient protein expression.
What organism is RFP from?
Discosoma sp
Red fluorescent protein (RFP) is a fluorophore that fluoresces red-orange when excited. Several variants have been developed using directed mutagenesis. The original was isolated from Discosoma, and named DsRed….Red fluorescent protein.

What is a MitoTracker?
How do you dissolve a MitoTracker?
Dissolve one vial (50 µg) of MitoTracker Green FM (Invitrogen M7514) in DMSO to prepare a stock solution of 1 mm. Cover with aluminum foil to minimize light exposure. Store at or below −20°C.
How long does MitoTracker last?
The experiment will last approximately 48 hours.
What is the meaning of protocol in science?
Definition of protocol 1 : an original draft, minute, or record of a document or transaction 4 : a detailed plan of a scientific or medical experiment, treatment, or procedure 1 : an official account of a proceeding especially : the notes or records relating to a case, an experiment, or an autopsy
When should I use celllight reagents?
When to use CellLight reagents. Use CellLight reagents when you want to label specific organelles or intracellular structures in live cells with minimal toxicity or chemical disruption. Follow the behavior of individual cells, multiplex with other CellLight reagents or organic dyes, and analyze in live cells or after fixation.
How do you label fluorescent proteins with celllight?
CellLight Fluorescent Protein Labeling. Invitrogen Molecular Probes CellLight reagents provide the easiest way to label specific structures in live cells with fluorescent proteins. Simply add the reagent to your cells, incubate overnight, and you’re ready to image in the morning.
What is the meaning of prōtokollon?
protocol and Politics. In Late Greek, the word prōtokollon referred to the first sheet of a papyrus roll bearing the date of its manufacture. In some instances, it consisted of a flyleaf that was glued to the outside of a manuscript’s case and provided a description of its contents.
