Calcium indicators

Calcium indicators are special tools used to measure calcium levels in cells and tissues. Calcium is an important signaling molecule in many biological processes, such as muscle contraction, nerve transmission, and hormone secretion. These indicators often change color or emit light when calcium binds to them, allowing scientists to visualize and track calcium dynamics in real time. By using these indicators, researchers can better understand how cells function and respond to various stimuli, which can help in studying diseases and developing new treatments.
