• To highlight key considerations for optimizing FN experiments.

Main Methods:

• Review of critical factors in FN experiments.
• Discussion of affinity-based labels, dyes, and multiplexing strategies.
• Exploration of live cell imaging and quantitative microscopy approaches.

Main Results:

• Optimal sample preparation and labeling are as critical as technological advances in FN.
• Consideration of methodological factors enhances FN effectiveness.

Conclusions:

• FN is an exquisite tool for numerous biological applications when experimental factors are optimized.
• Effective FN relies on careful selection of labels, dyes, and imaging techniques.
