Calcium imaging Calcium imaging Calcium imaging is a scientific technique usually carried out in research which is designed to show the calcium (Ca) status of an isolated cell, tissue or medium. Calcium imaging techniques take advantage of so-called calcium indicators, fluorescent molecules that can respond to the binding of Ca ions by changing their fluorescence properties. Two main classes of calcium indicators exist: chemical indicators and genetically encoded calcium indicators (GECI). Calcium imaging can be used to optically probe intracellular calcium in living animals. This technique has allowed studies of calcium signalling in a wide variety of cell types and neuronal activity
Degree symbol the degree symbol (e.g., 10 °C). However, in many works with professional typesetting, including scientific works published by the University of Chicago Press or Oxford University Press, the degree symbol is printed with no spaces between the number, the symbol, and the Latin letters "C" or "F" representing Celsius or Fahrenheit, respectively (e.g., 10°C). This is also the practice of the University Corporation for Atmospheric Research, which operates the National Center for Atmospheric Research. Though not recommended, use of the degree symbol without a following Latin letter is done so without a space between the number and symbol (e.g., 10°);
