calcium ions

Ionomycin is an calcium ionophore and an antibiotic that binds calcium ions (Ca2+). It is produced by the bacterium Streptomyces conglobatus.It is used in research to raise the intracellular calcium level (Ca2+) and as a research tool to understand Ca2+ transport across biological membranes. Ionomycin promotes apoptosis and induces the activation of protein kinase C (PKC).

2,4-Dihydroxypyridine is a pyridine derivative that acts as a chelating agent binding to metal ions and forming complexes. It is used as a reagent for determining the concentration of various ions, such as calcium, magnesium and phosphate. It is also used to measure the rate of enzyme-catalyzed reactions. It is also used for the detection and quantification of proteins, carbohydrates and other biomolecules.
