| Application: | • Magnesium chloride hexahydrate has been used in wash buffer for the purification of protein from Saccharomyces cerevisiae. • It has been used for the preparation of extracellular (Ringer) solution for juxtacellular recording of single neurons in freely moving rats. • It has been used as a supplement to study effect of desiccation on bacterial viability. |
| Other Notes: | Reconstitution of membrane processes; Strongly enhances the vinblastine-induced tubulin self-association; Component of Dulbecco′s phosphate buffered saline for tissue culture; Component of culture media for Pseudomonas. In Salmonella Enrichment Broth acc. to Rappaport, inhibits normal intestinal flora. |
