What is an advantage of using a bacterial expression system for GFP production?

The choice of using a bacterial expression system for GFP production is highly favored due to the characteristic of high yield and rapid growth of bacterial cultures. Bacteria, such as Escherichia coli, can multiply quickly, often doubling in number every 20-30 minutes under optimal conditions. This rapid proliferation allows researchers to produce a large volume of protein in a relatively short amount of time, making the process efficient and economical.

In addition, bacterial systems are typically easier to scale up compared to other types of expression systems, such as mammalian cells, which can be more complex and slower to grow. The combination of high yield and quick production times means that researchers can obtain sufficient quantities of GFP for various experimental applications, thereby streamlining the purification process and accelerating research timelines.

While other options may provide useful attributes in different contexts, the unparalleled growth rate and resultant yield of bacterial systems make them especially advantageous for protein production like GFP.
