Среда PBS Phosphate Buffered Saline Buffer pH 7.2-7.5, 500 мл
PBS (phosphate buffered saline) is a balanced salt solution used in cell culture manufacturing and upstream process development. PBS acts as a buffer to help maintain pH in cell culture media. PBS is well suited for washing cells before dissociation, transporting cells or tissue, diluting cells for counting, and preparing reagents. PBS is formulated without calcium and magnesium. Servicebio balanced salt solutions are manufactured at a cGMP-compliant facility using water for injection, filtered through final 0.1 μm sterile filtration and aseptic filled in a Hundred-stage FFU. The filter integrity tests are performed before and after filtration. Each lot of PBS solutions are subjected to sterility test, pH, osmolality and endotoxin. The major character of PBS is as follows: l 2.7 mM KCl, 2.0 mM KH2PO4, 137 mM NaCl, 10 mM Na2HPO4, pH 7.2-7.5@25℃。 l Without calcium, magnesium, phenol red.
