Fluorescent Proteins
Since the isolation of the first naturally fluorescing protein from jelly fish in the 1960s, fluorescent proteins (FPs) have become integral to a wide range of biological/medical applications, allowing visualization of biomolecules and processes in living cells and tissues to a much greater degree than was previously possible. Extensive molecular engineering of naturally occurring FPs has led to several families of recombinant proteins tailored to specific biophysical and imaging purposes.
