| Product Name | Dulbecco's Phosphate-Buffered Saline Powder, 1×, with Calcium and Magnesium |
| Catalog No. | RERE-0369 |
| Description | Dulbecco's phosphate-buffered saline, frequently abbreviated D-PBS or DPBS, ranks among the most widely used buffering systems in cell culture work. This powder format is formulated with calcium and magnesium and dissolves to a 1× working solution spanning pH 7.2 to 7.4, suitable for washing cultured cells and other routine manipulations. Each litre of reconstituted solution carries 137 mM sodium chloride, 2.68 mM potassium chloride, 8.1 mM disodium hydrogen phosphate, 1.47 mM potassium dihydrogen phosphate, 1.8 mM calcium chloride and 3.98 mM magnesium ions. Simply dissolve the powder in water; autoclave or filter-sterilise if an aseptic preparation is required. |
