Figure 3. True colors of fluorescent proteins in worms and their emission spectra.

Figure 3.

A) Emission-based, filter-free images of worms expressing fluorescent proteins from either the Daf-21(mEGFP and mCherry) or Eft-3 (mTagBFP2, mCerulean3, mTFP, mCitrine, MKO2, mTagRFP-T, mScarlet, mNeptune) promoters.. Each fluorescent protein and the peak emission measured for that fluorescent protein is listed on the left. The corresponding worm is shown on the right. The red arrow indicates concentrated protein in nuclei of intestine cells in mTFP worms. All of the fluorescent proteins we looked at show this property. B) The histogram pictured here shows the emission intensity as a function of wavelength for each fluorescent protein we measured in vivo in C. elegans.
