What is the function of mNeonGreen?
mNeonGreen worked very well to tag proteins, label specific subcellular compartments, and report expression patterns of low-expression genes. We conclude that mNeonGreen represents a valuable alternative to complement standard GFPs, and we have prepared a plasmid set for its dissemination in the research community.
What is TagBFP?
TagBFP is a basic (constitutively fluorescent) blue fluorescent protein published in 2008, derived from Entacmaea quadricolor. It is reported to be a very rapidly-maturing monomer with very low acid sensitivity.
What organism is mNeonGreen from?
mNeonGreen: a yellow-green fluorescent protein mNeonGreen is a yellow-green fluorescent protein that was derived from the tetrameric yellow fluorescent protein (LanYFP) from the marine invertebrate Branchiostoma lanceolatum in 2012.
What is the size of mNeonGreen protein?
26.6 kDa
mNeonGreen consists of 237 amino acids, which translates into 26.6 kDa molecular weight. This size, but not sequence, is very similar to EGFP that comprises 239 amino acids and is 26.9 kDa.
What is the brightest blue fluorescent protein?
The brightest GFPs recently developed are Clover (4), mClover3 (5), and mNeonGreen (6), but they exhibit only minor differences in quantum yield (QY) and extinction coefficient (EC) values, suggesting that these properties may have reached a local maximum in FPs that contain a GYG-type chromophore (5).
What is the PDB code for the template structure of mNeonGreen?
RCSB PDB – 5LTP: Structure of the Yellow-Green Fluorescent Protein mNeonGreen from Branchiostoma lanceolatum at the acidic pH 4.5.
Why is DAPI used?
It is used extensively in fluorescence microscopy. As DAPI can pass through an intact cell membrane, it can be used to stain both live and fixed cells, though it passes through the membrane less efficiently in live cells and therefore provides a marker for membrane viability….DAPI.

Why do we use DAPI?
A simple-to-use fluorescent stain, 4′,6-diamidino-2-phenylindole (DAPI), visualizes nuclear DNA in both living and fixed cells. DAPI staining was used to determine the number of nuclei and to assess gross cell morphology.
What is the excitation and emission maxima of MTFP1?
Because the excitation and emission maxima were red-shifted (462 nm and 492 nm, respectively), they gave this a teal classification rather than cyan and named the protein mTFP1. The researchers recommend using mTFP1 with a 445/30 nm excitation filter, a 470 nm beamsplitter, and a 495/30 nm emission filter.
What is MTFP1?
mTFP1 is a basic (constitutively fluorescent) cyan fluorescent protein published in 2006, derived from Clavularia sp.. It has low acid sensitivity.
What is the best filter size for MTFP1?
The researchers recommend using mTFP1 with a 445/30 nm excitation filter, a 470 nm beamsplitter, and a 495/30 nm emission filter.
What is the excitation maxima of mneongreen?
Its excitation maxima is at 506 nm and its emission maxima is at 517 nm. Because mNeonGreen wavelengths lie between the green and yellow fluorescent protein wavelengths, it can be imaged either with standard green fluorescent protein filters or yellow fluorescent protein filters, with no or minimal reduction in emission readout, respectively.
