SpletIntroduction. Phosphate buffered saline (a.k.a PBS or PBS buffer) is one of the most used buffers since it is isotonic to most of the cells. We have placed reagents required for preparation in a table. This table also contains information on molarity of each reagent and amount of salt (s) to be added for making 500mL and 1L of 1X and 10X. SpletVirus at the same concentration was also stored under the same conditions in a traditional standard liquid formulation [100 mM PBS (pH 7.0), 10% v/v glycerol, control A) commonly used to compare novel formulations (32, 33) and titer assessed over time for comparison. The amount of infectious virus recovered from films stored at 37°C was ~ 97 ...
