Author: Wang, Emily S. Fluorescent protein quick guide. Fluorescent protein development strategies are focused on fine- tuning the photophysical properties of blue to yellow variants derived from the Aequorea victoria jellyfish, as well as on the development of monomeric versions derived from other organisms that emit in the yellow- orange to far- red regions of the visible light spectrum.

In addition, you will also need to choose fluorescent proteins that can be. Fluorescent proteins ( FPs) have been used as protein tags since the mid- 1990s mainly for cell biology and fluorescence microscopy. The process responsible for the fluorescence of fluorescent probes and other fluorophores is illustrated by the. A fluorophore is attached to reactive group A. Why is the Bradford Assay a superior method for determining protein concentration compared to other protein concentration methods such as taking an absorbance at 280 nm? These tags have not only revolutionized cell biology by enabling the imaging of almost any protein, they are also used in biochemical applications.

To choose a set of fluorescent proteins to be imaged together, you will need to consider the same factors as when choosing an individual fluorescent protein ( brightness, photostability, and so on; see the previous blog post for more discussion of these factors).

Fluorescent proteins are genetically encoded tools that are used extensively by life scientists. For example, one popular donor, enhanced cyan fluorescent protein ( ECFP), has fivefold less brightness than its yellow acceptor partner, EYFP.
