GFP derivatives

GFP derivatives are modified versions of the original Green Fluorescent Protein, a natural protein that glows green under specific light. Scientists alter GFP’s structure to create derivatives with different properties, such as changing their color (like yellow or cyan), increasing brightness, or improving stability under various conditions. These modified proteins help researchers observe and track biological processes, like how cells grow or how proteins move within a cell, in real-time. Essentially, GFP derivatives are customizable tools that make it easier to study complex biological systems visually and non-invasively.
