What is mCherry fluorescence?

mCherry is a basic (constitutively fluorescent) red fluorescent protein published in 2004, derived from Discosoma sp.. It is reported to be a very rapidly-maturing monomer with low acid sensitivity.

What is the difference between EGFP and GFP?

The main difference between GFP and EGFP is that the GFP (stands for Green Fluorescent Protein) is a protein that exhibits bright green fluorescence when exposed to blue light whereas the EGFP (stands for Enhanced Green Fluorescence Protein) exhibits stronger fluorescence than GFP.

What is tandem dimer?

tdTomato is a genetic fusion of two copies of the dTomato gene (2) which was specifically designed for low aggregation (1). Its tandem dimer structure plays an important role in the exceptional brightness of tdTomato (Table I). Its excitation and emission maxima occur at 554 nm and 581 nm, respectively (1).

What is the best red fluorescent protein?

mCherry is the most widely used and cited red fluorescent protein owing to its fast maturity, stability, and resistance to photobleaching. mCherry and DsRed-Monomer are ideal for tagging proteins with diverse functions and/or subcellular localization patterns.

How do you detect mCherry?

It’ll depend on the flow cytometer you have access to but to best detect the mCherry signal excite with the yellow-green laser at 561 nm and detect in the PE-TexasRed channel with a 610/20 bandpass filter.

Why is mCherry used?

mCherry belongs to the group of fluorescent protein chromophores used as instruments to visualize genes and analyze their functions in experiments. Genome editing has been improved greatly through the precise insertion of these fluorescent protein tags into the genetic material of many diverse organisms.

Does GFP antibody recognize EGFP?

GFP antibody (ab6556) is reactive against all variants of Aequorea victoria GFP such as S65T-GFP, RS-GFP, YFP, CFP, RFP and EGFP.

At what wavelength does GFP fluorescence?

GFP can be excited by the 488 nm laser line and is optimally detected at 510 nm.

What color is Cy3?

The Cy3 dye is a traditional orange-fluorescent label for protein and nucleic acid conjugates used for imaging, flow cytometry, and genomic applications.

What is red fluorescent protein used for?

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.

Can GFP antibody detect mCherry?

A: The anti-GFP antibody was made using the N-terminal of GFP as an antigen and will not react with RFP proteins dsRED or mCherry, since their sequences are so different. Q: Can this antibody be used for immunostaining? A: Yes, this antibody may be used for immunostaining.

How is mCherry used to study fluorescent proteins?

Fluorescent proteins are used to tag components in the cell, so they can be studied using fluorescence spectroscopy. mCherry absorbs light between 540-590 nm and emits light in the range of 550-650 nm. mCherry belongs to the group of fluorescent protein chromophores used as instruments to visualize genes and analyze their functions in experiments.

How are mCherry and mRFP1 fused in cells?

To test whether the introduction of GFP -type termini into mRFP variants would benefit fusion proteins expressed in mammalian cells, we fused mRFP1 and mCherry to the N terminus of α-tubulin. In most HeLa cells, expression of mRFP1 -α-tubulin resulted in diffuse cytoplasmic fluorescence rather than proper incorporation into microtubules.

When to use mCherry as an intracellular probe?

mCherry is used in fluorescence microscopy as an intracellular probe. However, when a protein is tagged by fusion to a fluorescent protein, interactions between them can undesirably disturb targeting or function.

Can a mCherry fusion be incorporated into a microtubule?

In most HeLa cells, expression of mRFP1 -α-tubulin resulted in diffuse cytoplasmic fluorescence rather than proper incorporation into microtubules. However, mCherry -α-tubulin fusions were successfully incorporated into microtubules in most cells, similar to results seen with GFP -coupled tubulin.
