Calcium imaging a single wavelength or two wavelengths expressed as a ratio (ratiometric indicators). The derived fluorescence intensities and ratios are plotted against calibrated values for known Ca levels to learn Ca concentration. Light field microscopy methods extend functional readout of neural activity capabilities in 3D volumes. 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
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
