Question

Which of the following is NOT a commonly used fluorophore?
A)GFP
B)CFP
C)EPuce
D)EYFP
E)mBanana

Accepted Answer

EPuce is not a commonly used fluorophore in biological research. However, the other options are all commonly used fluorescent proteins for imaging and visualization of proteins and organelles in live cells. GFP (Green Fluorescent Protein), CFP (Cyan Fluorescent Protein), EYFP (Enhanced Yellow Fluorescent Protein), and mBanana (a yellow-green fluorescent protein) are all commonly used fluorophores.
