Background:

  • Recent advances in molecular biology, organic chemistry, and materials science have led to novel fluorescent probes.
  • These probes are crucial for advanced imaging techniques in cell biology.

Purpose of the Study:

  • To review the benefits and limitations of fluorescent probes for protein studies.
  • To discuss protein detection in live versus fixed cells.

Main Methods:

  • Review of small organic fluorescent dyes.
  • Review of nanocrystals (quantum dots).
  • Review of autofluorescent proteins and genetically encoded tags.
  • Discussion of combined microscopy techniques.

Main Results:
