What is the sequence of GFP?
In GFP the fluorophore originates from an internal tripeptide sequence (Ser‐Tyr‐Gly) which is post‐translationally modified to the structure shown below, a 4‐(p‐hydroxybenzylidene)‐imidazolidin‐5‐one.
How do you visualize fluorescent proteins?
DsRed fluorescent protein variants can often be visualized with standard TRITC filter combinations, as well as many of the longpass and bandpass sets designed for other probes absorbing in the green region of the visible spectrum.
How do you choose FRET pairs?
When choosing FRET pairs, choose the highest quantum yield donor, the highest absorbing acceptor, and fluorophores having substantial overlap in their spectral profiles. This combination will help maximize the FRET signal.
How many base pairs is GFP?
One interesting candidate gene that fulfills these requirements is the gene-encoding green fluorescent protein (GFP). It was originally isolated from the jellyfish Aquorea victoria. The GFP cDNA consists of 730 bp, which encode a 238 amino acid protein with a molecular weight of 27 kD (2).
Can you see GFP with UV light?
It is easy to find out where GFP is at any given time: you just have to shine ultraviolet light, and any GFP will glow bright green.
What is the Forster distance?
The Förster distance represents the molecular separation at which energy transfer is 50-percent efficient. For measurable FRET to occur, several requirements must be met. Among these is a strong dependence on the physical distance between the donor and acceptor fluorophores, which is limited to only a few nanometers.
What is FRET protein?
FRET occurs when donor fluorescent molecules tagged to a protein of interest transfer their excited-state energy to acceptor molecules tagged to another protein of interest. The need to accurately and easily measure FRET led to our development of photoswitching FRET (psFRET).
What are the sequence rules in MPEP?
See MPEP § 2422.04 for additional information. The sequence rules define a set of symbols and procedures that are both mandatory and the only way that an applicant is permitted to describe information in the sequence listing about a sequence that falls within the definitions used in the rules.
Can I add an excerpt to my EBFP?
No excerpts have been added for EBFP Excerpts are snippets from publications that capture key information about this protein that does not easily fit into one of the existing fields (such as a summary, motivation, or observation). Add an excerpt Primary Reference

What is EBFP made of?
Add to favorites2 EBFP is a basic (constitutively fluorescent) blue fluorescent protein published in 1998, derived from Aequorea victoria. Oligomerization
