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
Calcium lactate 75% relative humidity. Calcium lactate can be prepared by the reaction of lactic acid with calcium carbonate or calcium hydroxide. Since the 19th century, the salt has been obtained industrially by fermentation of carbohydrates in the presence of calcium mineral sources such as calcium carbonate or calcium hydroxide. Fermentation may produce either D or L lactate, or a racemic mixture of both, depending on the type of organism used. Calcium lactate has several uses in human and veterinary medicine. Calcium lactate is used in medicine as an antacid. Calcium lactate is also used to treat hypocalcaemia (calcium deficiencies). It can
