Manganese (II) chloride (MnCl2) might play a key role in integrin activation. Manganese is indispensable for brain function and is an essential cofactor for several key enzymes like superoxide dismutase and enzymes involved in neurotransmitter synthesis. Manganese can modulate iron and calcium homeostasis. Manganese is also used in the magnetic resonance imaging to increase contrast while examining neuronal connections and brain cytoarchitecture. High levels of manganese is toxic to central nervous system and causes Parkinsons like symptoms called as manganism. MnCl2 has been used in reverse transcription reaction mix to enhance the template-switching efficiency.
MnCl2 solution is a source of manganese ions and has a variety of biological uses. In biochemistry, it can be used as a cofactor in restriction enzymes, such as BamH and EcoR V. In molecular biology, Mn2+ can be substituted for Mg2+ as a divalent metal ion to facilitate DNase I activity in presence of Ca2+.
