Green Fluorescent Protein Applications

The video lecture discusses the green fluorescent protein (GFP), its discovery in jellyfish, and its applications in biotechnology. GFP is used as a reporter gene to track gene expression and visualize cellular processes. The lecture also covers the use of GFP in microscopy for imaging microtubules and other cellular structures. Additionally, it explains the modifications of GFP to produce different fluorescent colors for various research purposes.
