Fluo-3

Fluo-3 is a specialized dye used by scientists to detect calcium levels inside cells. Calcium ions play a vital role in many cellular processes, such as muscle contraction and nerve signaling. When Fluo-3 enters a cell, it binds to calcium ions, causing it to glow with a bright fluorescence. This change in brightness can be measured using specific instruments, allowing researchers to monitor calcium fluctuations in real-time. Fluo-3 is valuable because it provides a visual and quantitative way to study how cells communicate and respond to various stimuli.
