Ca2+ indicators

Ca2+ indicators are special tools used to measure the concentration of calcium ions (Ca2+) in cells and tissues. Calcium ions play a crucial role in various cellular processes, including muscle contraction, nerve signaling, and cell growth. These indicators often change color or fluorescence when they bind to calcium, allowing researchers to visualize and track changes in calcium levels in real-time. This helps scientists understand how cells respond to different stimuli and can aid in studying various health conditions, making Ca2+ indicators important in both research and medical applications.
