Merck, B4059-500ML, Barium hydroxide solution

Application
Barium hydroxide may be used in the development of formulations for the purification of materials such as heteropolysaccharide-protein biopolymers and the release of long-chain bases (LCB) from biological samples. Barium hydroxide solution may be used for protein precipitation in turbid fluids such as whole blood in assays based on the Somogyi-Nelson method.
Used in conjunction with zinc sulfate to deproteinize via barium sulfate precipitation whole blood, plasma, or serum samples which are colored or turbid. The resulting supernatant or filtrate is then available for subsequent analysis of glucose by Somogi-Nelson method.
