Primed conversion: The emerging player of precise and nontoxic photoconversion

Area of Science:

• Biophysics
• Molecular Biology
• Optical Imaging

Background:

• Photoconvertible fluorescent proteins (PFPs) are crucial for advanced imaging.
• Traditional PFP conversion methods use violet or near-UV light, limiting applications.
• Primed conversion, reported in 2015, utilizes blue and red-to-far-red light for PFP conversion.

Purpose of the Study:

• To review the principles and applications of primed conversion.
• To focus on its utility in single-cell labeling and lineage tracing.
• To discuss future developments in primed conversion imaging.

Main Methods:

• Review of fundamental principles of fluorescence and PFPs.
• Historical perspective of lineage tracing techniques.
• Analysis of molecular requirements for primed conversion.
• Demonstration of dual-color high-fidelity lineage tracing.

Main Results:

• Primed conversion offers advantages over traditional methods for PFP conversion.
• The technique enables high-fidelity, dual-color lineage tracing.
• It provides a powerful tool for precision optical imaging.

Conclusions:

• Primed conversion is a significant advancement in optical imaging and lineage tracing.
• The technique has broad potential applications in studying development and disease progression.
• Future developments will further enhance the primed conversion imaging toolkit.
