New Aequorea Fluorescent Proteins for Cell-Free Bioengineering

Area of Science:

• Biochemistry
• Synthetic Biology
• Biotechnology

Background:

• Fluorescent proteins are crucial reporters in cell-free systems.
• A new subset of fluorescent proteins was recently discovered in *Aequorea* species.
• Previous characterization of these proteins was limited to *in vivo* studies.

Purpose of the Study:

• To characterize and validate novel *Aequorea* fluorescent proteins for cell-free applications.
• To assess the utility of these proteins in synthetic cell expression platforms.

Main Methods:

• Characterization of fluorescent proteins *in vitro*.
• Validation studies in various cell-free systems.
• Assessment of protein performance in synthetic cell environments.

Main Results:

• Successful validation of the new *Aequorea* fluorescent proteins in cell-free systems.
