Dulbecco’s Phosphate Buffered Saline (DPBS) is a balanced salt solution. It is particularly used to maintain viability of cells for a short time instead of promoting their growth. During interval period we maintain osmotic balance and physiological pH to protect cellular integrity. So, DPBS serves as an isotonic saline solution or buffer for washing cells and tissues like in chromatographic procedures where incubation is not necessary.<\/p>\n

To remove this pathogen, we pass the buffer \u00a0through the PurMa\u2122 Endotoxin Elimination Column (Cat# P6H1216251). Furthermore, in our proprietary column,\u00a0 we covalently conjugate Sepharose 6B\u00a0 to an endotoxin-specific absorbent. We finally\u00a0 eliminate the endotoxin residual by passing the unbound fraction three times through 0.1\u00b5m filters.<\/p>\n \u00a0<\/strong><\/span>References: <\/strong><\/span><\/p>\n <\/p>\nPurMa Biologics Manufactures Several Grades of Buffers<\/strong><\/h3>\n
