With the 2008 Nobel Prize in Chemistry, the value of the discovery and development of fluorescent proteins (FPs) has been well recognized and appreciated. However, the research on FPs has not reached its utmost potential. Instead, there have been relentless endeavors to find the "perfect" FPs since their discovery just over a decade ago. Bright, photostable, monomeric, and fast-maturing FPs are being sought in all spectral regions. Those that work well as fusions or in fluorescent resonance energy transfer (FRET) see ever-increasing use as molecular markers or rulers.

Novel microscopy techniques that can image with resolutions of ~10nm, previously only possible with electronic microscopy, rely on a family of FPs called “photoactivable FPs” or “photoswitchable FPs”. Such techniques include: PALM for Photoactivated Localization Microscopy and SIM for Structure-Illumination Microscopy.
There are 5 different FPs currently available and dozens more in the pipeline. The FPs currently available are:

• 
  mTFP1, a bright cyan FP with extremely high confocal photostability (2,721s) and the best FRET donor suggested by results in various FRET experiments from several groups;

• 
  mWasabi, a green derivative of mTFP1 that is twice as bright as EGFP;

• 
  LanYFP (from Lancelet), the brightest FP ever. Read more
• 
  mNeonGreen, the brightest monomeric fluorescent protein to date. Read More
• 
  green-to-red photoconvertible FP's (pcFP), monomeric pcFPs which include: mClavGR2, mClavGR3, and mMaple, All of which are high performance imaging tools with superior qualities suitable for super resolution imaging.

They have been integrated into the many different platforms and applications, such as lentivirus, retrovirus, baculovirus, RNA interference, bicistronic expression, organelle marker and promoter test constructs. Most FPs will be provided in the formats of a Plasmid, Pre-Packaged Virus, Recombinant Proteins, Custom Assay Development, and Patent Sublicensing.

GFP-Trap® is an immobilized GFP-binding protein derived from camelid single domain antibodies, and has been verified as a robust tool for many different immunoprecipitation assays.

In addition to the GFP-Trap and RFP-Trap, Allele Biotech provides more conventional antibodies against certain FPs, such as a Mouse Monoclonal Antibody against GFP, Rabbit Polyclonal Antibodies against GFP, a Rat Monoclonal Antibody [3H9] against GFP, and a Rat Monoclonal Antibody [5F8] against RFP.
