Beschreibung
Lithium acetate (CH₃COOLi) is a salt of lithium and acetic acid.
Chemische Eigenschaften
solid
Verwenden
Lithium acetate (LiOAc) is a lithium source and a doping salt which can be used in the preparation of plasticized polymer electrolytes for lithium-ion batteries. It can be used as a monovalent cation, which improves the transformation efficiency of Saccharomyces cerevisiae.
Verwenden
Lithium acetate is used in the laboratory as buffer for gel electrophoresis of DNA and RNA. It has a lower electrical conductivity and can be run at higher speeds than can gels made from TAE buffer (5-30V/cm as compared to 5 - 10 V / cm). Lithium boric acid or sodium boric acid are usually preferable to lithium acetate or TAE when analyzing smaller fragments of DNA (less than 500 bp) due to the higher resolution of borate-based buffers in this size range as compared to acetate buffers.
Lithium acetate is also used to permeabilize the cell wall of yeast for use in DNA transformation. It is believed that the beneficial effect of LiAc is caused by its chaotropic effect denaturing both DNA, RNA and proteins.
Verwenden
Lithium acetate hydrate is used in the laboratory as buffer for gel electrophoresis of DNA and RNA. It is also used to permeabilize the cell wall of yeast for use in DNA transformation. It is a metal acetate for proteomics research.
Definition
ChEBI: An acetate salt comprising equal numbers of acetate and lithium ions.
Flammability and Explosibility
Non flammable
Sicherheitsprofil
Poison by intravenous route. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALUMINUM and LITHIUM COMPOUNDS.
